9 SET MODES D Power save (P SAVE) The power save function allows you conserve battery life by selecting the duty cycle of the receiver. Select the ratio of the power save time to the standby time. (default: Auto) • OFF : Turns the function OFF. • 2 : Sets the duty cycle to 1:2. • 8 : Sets the duty cycle to 1:8. • 16 : Sets the duty cycle to 1:16. • 32 : Sets the duty cycle to 1:32. • Auto : Transceiver s��e�t�s�"�1��:2��" �d�u��ty��r�a�t�io���w�h�e��n��r�e�c�e�i�v�i�n�g��n�o� signal for 5 seconds, then it sets "1:16" after 60 sec- onds has past. No signal Circuit ON 5 sec. 125 msec. 1000 msec. Circuit OFF 62.5 msec. 60 sec. D Voltage indication (VOLT) The power voltage, battery voltage or external power supply voltage, is displayed at power ON. This setting can be turned ON or OFF. (default: On) • OFF : The power voltage display is skipped. • On : The power voltage is displayed at power ON. D DTMF speed (DTMF-S) Select the desired DTMF transmission speed from 100, 200, 300 or 500 msec. (default: 100) • 100 : 100 msec. interval; 5.0 characters per second • 200 : 200 msec. interval; 2.5 characters per second • 300 : 300 msec. interval; 1.6 characters per second • 500 : 500 msec. interval; 1.0 character per second NOTE: Power save function is disabled when using an external power supply (more than 10 V DC). 61
