OPTIONAL DTMF REMOTE

■ External DTMF Remote

To operate External DTMF Remote, an optional UT-55 and a 144 MHz or 430 (440) MHz transceiver with a DTMF encoder are necessary.

(1) Pre-operation

1) Set the MAIN band frequency for operation and the SUB band frequency for receiving of a DTMF control signal.

• An optional tone squelch function can be used for SUB band to increase remote control reliability.
• Set the para-watch condition when using the same band for External DTMF Remote. (p. 44)

2) Program a 3-digit password into code channel 5, if required. (p. 32)

- The code channel 5 has been programmed "000" as initial value. If you do not require the password, set the channel as "receive inhibit."

3) Prepare a transceiver used as a controller:

• Set the operating frequency equal to the SUB band frequency of the IC-2410A/E/H.
• Turn ON the subaudible tone encoder and set the tone frequency when the IC-2410A/E/H uses an optional tone squelch function.

(2) Operation

1) Push and hold [PGR/CS] until "REMOTE" appears to select standby for the remote control.
2) From the controller transceiver, transmit a DTMF code to activate External DTMF Remote as follows.

① When a password has been set, push [B], the 3-digit password and [#].
② When a password has not been set, push [B] and [#].

- "REMOTE" and "SUB" blink.

3) Transmit the following DTMF code to control from the controller transceiver. See p. 42 for details.

CPU resetting

The function display may occasionally display erroneous information, (e.g., when first applying power). This may be caused externally by static electricity or other factors.

If this problem occurs, turn power OFF. After waiting a few seconds, turn power ON again. If the problem continues, perform the following procedure.

NOTE: CPU resetting CLEARS all memory information, and initializes all values.

1) Turn power OFF.
2) While pushing [SET] and [MW], turn power ON.
- All segments appear on the function display, and the CPU is reset.

Cleaning

If 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 can damage the transceiver surfaces.

■ Fuse replacement

If the fuse blows or the transceiver stops functioning, find the source of the problem if possible, and replace the damaged fuse with a new, rated fuse as shown in the diagram below.

• REPLACING A FUSE
  

Fuse (15A)

■ Backup batteries

The IC-2410A/E/H and HM-56 are equipped with separate lithium backup batteries for retaining memory information.

The life of the lithium backup batteries is usually more than 5 years. When the batteries are exhausted, the transceiver operates normally but the CPU cannot retain memory information.

NOTE: DO NOT attempt to replace the backup batteries yourself. They can be replaced only by an authorized Icom Dealer or Service Center.
