User manual ICOM IC-471A-E

[. . . ] In this case, the transceiver alerts you via beeps. 11) i I WATER-RESISTANT* CONSTRUCTION Water-resistant* construction is employed. *Meets JIS water-protection specification grade 4. I GROUP MODE (BUILT-IN CTCSS: Continuous Tone Coded Squelch System) CTCSS encoder/decoder are standard, providing quiet stand-by. Audio (voice) signals are output only when a signal with matched CTCSS tone signal is received--very helpful for group communications. [. . . ] If you want to be able to charge the battery pack more than 300 times, the following points should be observed: 1. The charging period should be less than 48 hours. Use the battery until it becomes almost completely exhausted under normal conditions. We recommend battery charging just after transmitting becomes impossible. ` Charging precautions NEVER attempt to charge dry cell batteries. This will cause internal liquid leakage and damage the battery case and transceiver. Recommended temperature range for charging: + 10°C to + 40°C (or + 50°F to +104°F). ` About the battery pack D Operating period Depending on the attached battery pack, the operating period of the transceiver varies. 7 for operating period details. D Battery pack life If your battery pack seems to have no capacity even after being fully charged, completely discharge it by leaving the power ON all day. Then, fully charge the battery pack again. If the battery pack still does not retain a charge (or very little), a new battery pack must be purchased. 6 3 BATTERY PACKS ` Charging connections D Rapid charging with the BC-119L/BC-119+AD-89 q Insert the optional AD-89 DESKTOP CHARGER ADAPTER into the charging slot of the BC-119. · The BC-119L comes preinstalled with the AD-89 CHARGING ADAPTER. w Insert the battery pack, either by itself or attached to the transceiver, into the charger. (See BC-119/L instructions. ) IC-471A-E BP-202 * *NOTE: Put the Ni-Cd battery adapter into the AD-89 rear slot when the BP-202 is attached to the transceiver. AD-89 AC adapter BC-119 7 BASIC OPERATION ` Power ON Push [POWER] for 1sec. Group mode operation provides communication with silent standby since you will only receive calls from group members using the same group number. First of all, set the same group code number for all group member's transceivers. Turn ON the group mode operation: q Push [MODE] to enter set mode. · " --- " (group mode OFF) appears on the display. w Push [UP]/[Y] or [DOWN]/[Z] to select the desired code number. e Push [MODE] to set the group code number. w w UP R POWE MODE DO W N q Cancel the group mode operation: q Push [MODE] to enter set mode. · Code number disappears on the display. w Push [UP]/[Y] or [DOWN]/[Z] to select " --- " (group mode OFF). 13 RING FUNCTION ` Smart-Ring 7 The ring function has an answer back feature. This allows you to confirm whether or not a call has reached the receiving party even if the operator is temporarily away from the transceiver. q Set the same group channel number for all of your group transceivers. (See left. ) w While pushing [PTT], push [UP]/[Y] . [. . . ] All IC-471A-E's operating on the same operating channel will answer back to your call in your communication area. ` Low battery indicator Appears when the battery is nearing exhaustion. · A warning beep is emitted while turning the power ON. Appears and blinks when battery replacement is necessary. 17 OTHER FUNCTIONS 8 ` LCD backlight Automatically turns ON for 5 sec. when you push any key, except [PTT]. ` Auto power save The power save function reduces the current drain to conserve battery power.
