BATTERY PACKS ‘ ‘ Battery pack replacement Before replacing the battery pack, the volume control MUST be ro- tated fully counterclockwise, until a click is heard, to turn the power OFF. • Push the battery re- lease forward, then pull the battery pack upward with the trans- ceiver facing you.
BATTERY PACKS ‘ ‘ Battery charging D Rapid charging with the BC-144 The optional BC-144 provides rapid charging of optional battery packs. The following are additionally required: • One AD-99 and an AC adapter (depending on version) Turn power Check orientation OFF.
BATTERY PACKS ‘ ‘ Charging NOTE Prior to using the transceiver for the first time, the battery pack must be fully charged for optimum life and operation. • Recommended temperature range for charging: +10°C to +40°C (50°F to 140°F). • Use the supplied charger or optional charger (BC-121/BC-144 for rapid charging, BC-137 #11/BC-146 for regular charging) only.
PROGRAMMABLE FUNCTIONS ‘ ‘ General In the following explanations, programmable function names are bracketed, the specific switch used to activate the function depends on programming. D D KEYPAD LOCK FUNCTION This function locks access to all programmable switches (except the switch assigned for the lock function). Push and hold the [LOCK] switch for 1 sec.

PROGRAMMABLE FUNCTIONS D D MONITOR AUDIBLE FUNCTION The monitor function allows you to open the transceiver’s squelch manually to check whether a channel is busy or not. The trans- ceiver has 2 conditions for receive standby: Audible condition: This condition mutes audio ONLY when no carrier is present.
PROGRAMMABLE FUNCTIONS • The emergency call is repeatedly transmitted at pre-programmed intervals. D D DISPLAY LIGHTING The function display has 3 backlight conditions. : No backlight is available. AUTO : When any key is pushed, the backlight turns ON for 5 sec.
CONVENTIONAL OPERATION ‘ ‘ Call procedure When your system employs tone signalling (excluding CTCSS and DTCS), the call procedure may be necessary prior to voice trans- mission. The tone signalling employed may be a selective calling system which allows you to call specific station(s) only and prevent unwanted stations from contacting you.
Push [M], [M] to automatically redial the last number called. • A high-pitched beep indicates that the number is accepted. *1: This function is available to for the IC-F3GS/IC-F4GS when the [Y]/[Z] keys are assigned the [M]/[ # ] key functions.
• If the other subscriber is on another call or out of range, you hear a fast busy signal and the call terminates automatically. *1: This function is available for the IC-F3GS/IC-F4GS when the [Y]/[Z] keys are assigned the [M]/[ # ] key functions.
MAINTENANCE ‘ ‘ Optional UT-96/ UT-105/ UT-108/ UT-109/ UT-110/ UT-111 and UT-113 installation You can install one of the following optional signaling units in the transceiver.
