11412 OTHER FUNCTIONS Power saveThe power save function reduces the current drain to con-serve battery power.The power save duty cycle, the ratio of receive circuit on toreceive circuit off during standby, can be set to automatic (de-fault), 1 : 1 (150 msec. : 150msec.), 1 : 4 (150 msec. : 600msec.), 1: 8 (150 msec. : 1200msec.) or OFF with “POWER SAVE” in setmode. (p. 88)• “AUTO” selects “1:1” duty ratio when receiving no signal for 5 sec.,then “1:4” 60 sec. after that. The ratio becomes “1:8” when no signalis received for another 60 sec. Auto power OFFThe transceiver can be set to automatically turn OFF after aspecified period with a beep when no switch is pushed.120 min., 90 min., 60 min., 30 min. and OFF can be speci-fied. The specified period is retained even when the trans-ceiver is turned OFF by the auto power-off function. To cancelthe function, select “OFF” in the auto power-off item in setmode.This can be selected with “AP OFF” in set mode. (p. 88) Auto power ONThe transceiver can be set to automatically turn ON after aspecified period. The timer can be selected within 30 min. to24 hrs. in 30 min. steps.This can be selected with “AP ON” in set mode. (p. 89)When operating with battery pack or case and the batteryis exhausted, auto power-on does not function.A slight current still flows in the circuits during standby con-dition of the auto power-on function.MENU screen ➪ SET MODE ➪ AP ON(Push [MENU/LOCK]) (Rotate [DIAL]†, then push [ï](5)†.)MENU screen ➪ SET MODE ➪ AP OFF(Push [MENU/LOCK]) (Rotate [DIAL]†, then push [ï](5)†.)150 msec.150 msec.60 sec. 60 sec.600 msec. 1200 msec.No signal5 sec.Circuit ONCircuit OFFMENU screen ➪ SET MODE ➪ POWER SAVE(Push [MENU/LOCK]) (Rotate [DIAL]†, then push [ï](5)†.)
