3711 OPERATOR CONVENIENCESNote: Use the PB-42L (Lithium battery pack) within the temperaturerange of –10°C ~ 50°C (14°F ~ 122°F).BATTERY SAVERBattery Saver extends the operating time of thetransceiver. It automatically activates when thesquelch is closed and no key is pressed for morethan 10 seconds. To reduce the battery consumption,it shuts the receiver circuit OFF for the programmedtime then momentarily turn it back ON to detect asignal.
