Häufig gestellte Fragen - IC-1201A ICOM

Das Gerät lässt sich nicht einschalten.

Überprüfen Sie die Polarität des Stromanschlusses – vertauschte Pole führen zu Funktionsstörungen. Möglicherweise ist die Sicherung durchgebrannt; ersetzen Sie diese nach Fehlerbehebung durch eine 10-A-Sicherung.

Kein Ton aus dem Lautsprecher.

Der Squelch-Regler könnte zu weit im Uhrzeigersinn gedreht sein – stellen Sie ihn auf die Rauschschwelle ein. Wenn das optionale UT-40 installiert ist, schalten Sie die Tonsquelch-Funktion aus.

Kontakt mit einer anderen Station ist nicht möglich.

Stellen Sie sicher, dass der Transceiver nicht auf Duplex geschaltet ist. Drücken Sie die DUP-Taste, bis die Anzeige 'DUP' oder 'DUP–' verschwindet, um den Simplex-Modus zu wählen.

Der Repeater kann nicht erreicht werden.

Prüfen Sie die programmierte Offset-Frequenz und die Subton-Frequenz (nur IC-1201A). Korrigieren Sie die Werte im SET-Modus. Beachten Sie, dass Offset- und Subton-Frequenzen für jeden Speicherkanal separat eingestellt werden.

Die Frequenz lässt sich nicht einstellen.

Die Tastensperre (LOCK) könnte aktiviert sein – drücken Sie die LOCK-Taste, um sie auszuschalten. Falls der Rufkanalmodus (CALL) aktiv ist, drücken Sie die CALL-Taste. Bei aktivierter RIT-/VXO-Funktion drücken Sie den Abstimmregler, um sie auszuschalten.

Der Scan startet nicht.

Der Squelch muss geschlossen sein – drehen Sie den SQL-Regler auf die Rauschschwelle. Bei programmiertem Scan dürfen die Scangrenzen A und B nicht identisch sein. Entfernen Sie ggf. die Speicher-Überspringen-Funktion von allen Kanälen.

Alle programmierten Speicher sind gelöscht.

Ein Datenfehler im CPU-RAM kann durch leere Backup-Batterie oder statische Entladung verursacht werden. Setzen Sie die CPU zurück (halten Sie SQL/MONITOR und LOCK gedrückt, schalten Sie ein) und programmieren Sie die Speicher neu. Ersetzen Sie die Backup-Batterie durch einen autorisierten Händler.

Wie setze ich die CPU zurück?

Schalten Sie das Gerät aus. Halten Sie die Tasten [SQL/MONITOR] und [LOCK] gedrückt und schalten Sie das Gerät wieder ein. Alle programmierten Daten werden gelöscht und die Frequenz 1295.000 MHz erscheint.

Wie reinige ich das Gerät?

Verwenden Sie ein trockenes, weiches Tuch. Vermeiden Sie chemische Reinigungsmittel wie Benzin oder Alkohol, da diese die Oberfläche beschädigen können.

Die Sicherung ist durchgebrannt – was tun?

Ermitteln Sie zuerst die Ursache des Kurzschlusses. Ersetzen Sie die Sicherung nur durch eine 10-A-Sicherung vom gleichen Typ. Ziehen Sie vor dem Wechseln das Netzkabel ab.

- AFC FUNCTION

Icom's advanced AFC* system automatically and immediately tunes the receive frequency or both transmit and receive frequencies to the frequency of the transmitting station when transmitting station is off frequency.

* Automatic Frequency Control

●HIGH SENSITIVITY

A GaAs FET MGF1502 is used for the RF front end circuit. The FET ensures low noise figure characteristics and superior sensitivity at less than 0.22 V for 12 dB SINAD.

•20 MEMORY CHANNELS

The IC-1201A/E contains 20 fully programmable channels and 1 call channel. Each channel can store all information required to work a repeater.

•SCAN FUNCTIONS

The IC-1201A/E is equipped with 2 scan functions: programmed scan and memory scan. A memory skip function is also included. In addition, priority watch waits for a call from a station while you're in contact with another station.

•STABLE OUTPUT POWER

The IC-1201A/E utilizes a newly designed Icom power module (SC-1066). This module steadily transmits 10 W of clean powerful output.

- POCKET BEEP FUNCTION

When the optional UT-40 TONE SQUELCH UNIT is installed, a 30 sec. alarm is emitted when a subaudible tone identical to your pre-programmed tone is received. This is especially convenient for busy schedules, etc.

- COMPACT BODY

Compact at just 140(W) x 40(H) x 200(D) mm [5.5(W) x 1.6(H) x 7.9(D) in]*, the IC-1201A/E will fit anywhere in your vehicle, making it the ideal traveller.

INSTALLATION

(1) LOCATION

Select a location for the transceiver that does not interfere with driving in any way. We recommend the location shown in the figure below.

Line drawing of a car interior with steering wheel and control panel (no text or symbols)

CAUTION

AVOID placing the transceiver in direct sunlight.

NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury.

DO NOT place the transceiver where hot or cold air blows directly on it.

(2) MOUNTING

After mounting the transceiver, be sure all screws have been tightened.

• MOUNTING THE TRANSCEIVER

Technical line drawing of an electronic device with multiple screw and housing components (no text or labels)

Technical line drawing of a mechanical component with no visible text or symbols

Adjust installation angle for good visibility.

1) Drill holes where the mounting bracket is to be installed.

- Hole size:

approx. 5.5 \~ 6 mm for nuts.

approx. 2 \~ 3 mm for self-tapping screws.

2) Insert the supplied screws, nuts and washers through the mounting bracket and tighten.

3) If the mounting location is not flat, use the supplied mounting support bracket.

4) Adjust the angle for the clearest view of the FUNCTION DISPLAY.

(1 inch = 25.4 mm)

(3) BATTERY CONNECTION

CAUTION:

NEVER connect the transceiver directly to a 24 V battery. DO NOT use the cigarette lighter socket for power connections. To prevent voltage drops, solder or crimp the cable lag when connecting the DC power cable to the battery.

(4) EXTERNAL POWER SUPPLY

Use a 13.8 V DC power source with more than 6 A capability. The optional PS-45 AC POWER SUPPLY is suitable for base station operation.

When using the transceiver as a base station, make sure a ground terminal of the power supply is grounded. Use the heaviest gauge wire or strap available and make the connection as short as possible.

3 INSTALLATION

(5) ANTENNA LOCATION

To obtain maximum performance from the transceiver, select a high-quality antenna and a good location.

(6) ANTENNA CONNECTOR

A Type-N antenna connector is used for the transceiver.

1) Slide the nut, washer, and rubber gasket over the coaxial cable and cut the end of the cable evenly.

2) Cut and remove 15 mm of the outer vinyl jacket, and fold the braid back over the clamp. The clamp end should be flush with the end of the vinyl jacket. Evenly trim the the braid ends.

Cut and remove 6 mm of the dielectric (the center conductor insulation).

3) Soft solder the center conductor. Install a center conductor pin and solder it.

4) Carefully slide the plug into place aligning the center conductor pin on the cable with the hole in the insulator inside the connector body.

5) Complete the assembly by screwing the nut into the connector body.

MODE CONSTRUCTION

4

The IC-1201A/E has 4 different modes for versatile multi-function operations.

(1) VFO MODE

(2) MEMORY MODE

(3) CALL CHANNEL MODE

(4) SET MODE

This mode is used for normal operations over the entire band.

This mode is used for operating the transceiver using memory channel contents. You can use 20 memory channels for programming (i.e., repeater frequencies, your ground frequency, etc.).

This mode provides 1 call channel operation separate from the memory channel. You can program the most often used frequency into this channel.

Use SET mode to program data. (p. 10)

Push the [SET] switch to select SET mode in the VFO mode. The display you last used appears.

Technical line drawing of four different mechanical components or assemblies, showing exploded and assembled views (no text or symbols present)

BACKUP BATTERY

The IC-1201A/E has a lithium backup battery for retaining memory information.

The usual life of the backup battery is approximately 5 years. When the battery is exhausted, the transceiver transmits and receives normally but the transceiver cannot retain memory information.

NOTE: Battery replacement should be done by an authorized Icom Dealer or Service Center.

CLEANING

When the transceiver becomes dusty or dirty, wipe it clean with a dry, soft cloth. Avoid the use of chemical agents such as benzine or alcohol as they may damage the surfaces of the transceiver.

ADJUSTMENT

Your IC-1201A/E has been thoroughly adjusted and checked at the factory before being shipped. Your transceiver warranty does not cover problems caused by unauthorized internal adjustments.
