Frequently Asked Questions - IC-A25C ICOM

How do I charge the battery pack for the first time?

Before using the transceiver for the first time, fully charge the BP-288 Li-ion battery pack using the supplied battery charger and power adapter. Charging time is approximately 3 hours. Remove the transceiver from the charger once fully charged.

How do I select the 121.5 MHz emergency frequency?

Press [F] then [121.5] to instantly select the emergency frequency 121.500 MHz. Press [CLR] to return to the previous frequency.

How do I adjust the squelch level?

Use the [SQL▲] and [SQL▼] keys to adjust the squelch level until background noise just disappears when no signal is present. The adjustment screen appears while setting.

What types of scans are available and how do I start a scan?

The IC-A25C supports VFO scan (scans all COM frequencies) and Memory channel scan (scans tagged memory channels in a group). Press [F] then [SCAN] to start scanning. Press [CLR] to stop.

How do I store a frequency into memory?

First set the desired frequency, then press [F] followed by [MW]. The Memory Write screen appears. Edit fields like Name, Type, and TAG Set if desired, then select the checkmark and press [ENT] to save.

How do I use the Weather Alert function?

Go to [MENU] > Radio Settings > Weather Alert and set it to ON. The transceiver will then monitor weather channels for a 1050 Hz alert tone. When an alert is received, WX and ALT blink alternately on the display.

Can I use a headset with this radio?

Yes, connect a third-party headset via the supplied headset adapter. Use a PTT switch with a 3.5 mm plug. Enable Side Tone to hear your transmitted voice: [MENU] > Sounds Settings > Side Tone.

Why doesn't the transceiver turn on?

Possible causes: battery exhausted (recharge), battery pack not correctly attached (reattach until it clicks), or blown fuse in the optional CP-20 cable (replace with FGB 8 A fuse).

How do I set up a Priority channel?

Go to [MENU] > Radio Settings > Priority CH. Press [ENT], select the desired memory channel from the group list, and press [ENT]. Then press [F] and [PRIO] to activate priority watch.

How do I clean and maintain the transceiver?

Keep the battery terminals clean by occasionally wiping them. Do not attach or detach the battery pack when the transceiver is wet or soiled to prevent water/dust ingress. Use a dry cloth for exterior cleaning.

The Side tone function outputs the transmitting audio to the headset connected to the transceiver.

NOTE:

When using the optional HM-231 HAND MICROPHONE, set the side tone output level to OFF. Otherwise, your voice will be heard from the speaker while transmitting.

Troubleshooting

PROBLEM POSSIBLE CAUSE SOLUTION REF.
The transceiver does not turn ON.	· The battery is exhausted.· The battery pack is not correctly attached.· The CP-20's fuse is blown.	· Recharge the battery pack.· Correctly reattach the battery pack.· Repair the problem, and then replace the fuse.	p. 3-2p. 1-3p. 13-2
Little or no sound comes from the speaker.	· Squelch level is set too high.· Volume level is set too low.	· Adjust the squelch level.· Adjust the volume level.	p. 4-2p. 2-2
You cannot transmit.	· Weather channel is selected,or VOR frequency is set.· The battery is exhausted.	· Set a COM band frequency.· Recharge the battery pack.	p. 4-2p. 3-2
“Locked” is displayed when you push keypad keys, or rotate [DIAL].	· The keypad and [DIAL] is locked.	· Push [F], and then push [→] to unlock the keypad.	p. 2-2
Scan does not start.	· All Memory channels in the selected group are not tagged.	· Tag memory channels on the Menu screen.	p. 8-4
No beep sounds.	· The beep output level is set to OFF.	· Adjust the beep output level on the Menu screen.([MENU] > Sounds Settings > Beep)	p. 11-7

◇Fuse replacement

If the fuse blows or the transceiver stop working while using it with the optional CP-20 CIGARETTE LIGHTER CABLE, correct the source of the problem. Then replace the damaged fuse with a new rated one (FGB 8 A), as shown to the right.
