4To install the battery case onto (or remove from) the transceiver, follow steps 1 to 3 for INSTALLING THE NiCd BATTERY PACK {page 2}.

◆Do not install the batteries in a hazardous environment where sparks could cause an explosion.

◆Never discard old batteries in fire because extremely high temperatures can cause batteries to explode.

Note:

◆It is recommended to use high quality alkaline batteries rather than manganese batteries to enjoy longer periods of battery life. Do not use commercially available NiCd batteries.

◆If you will not use the transceiver for a long period, remove the batteries from the battery case.

◆Do not use different kinds of batteries together.

◆When the battery voltage is low, replace all four old batteries with new ones.

The following table shows the approximate battery life (hours) relative to the transmit output power.
