7 3 BASIC OPERATION Dial select functionUse the dial select function to adjust the tuning behavior of the [Y]/[Z] keys—use 1 MHz tuning when you want to change the frequency in large increments; use regular tuning when you want to change the frequency in smaller incre- ments. qPush [V/M] to select VFO mode. wPush [V/M] for 2 sec. one or more times to select the de- sired tuning increment. - 1 MHz tuning, 100 kHz tun- ing or regular tuning steps can be selected. (see dia- grams at right) ePush any key...

Charging precautionsNEVER attempt to charge dry cell bat- teries. This will cause internal liquid leakage and damage the battery case and transceiver. NEVER connect two or more chargers at the same time. Charging may not occur under temper- atures of 10°C (50°F) or over tempera- tures of 40°C (104°F). When using BC-119:If the charge indicator flashes orange, vehicle bat- tery voltage is low and charging is not possible. Check the vehicle bat- tery voltage in this case. If the charge indicator flashes...

14 7 BATTERY PACKS About the battery packDOperating periodDepending on the attached battery pack, the operating period of the transceiver varies. Refer to the last page for battery pack specifications.DBattery pack lifeIf your battery pack seems to have no capacity even after being fully charged, completely discharge it by leaving the power ON overnight. 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...
