How to operate
Menu Locked function
To avoid operating unnecessary menu items often, you can set Menu Locked function on
through the programming software. This operation is proposed, if the radio shall be used by
persons which are not familiar with the menu functions or in cases, where the radio shall be
only used with restriction to most important functions to avoid risk of wrong adjustments.
See the following operation steps:
1. Setting password of switching Channel and frequency mode.
2. Set the working mode as Channel mode
3. Turn off operating menu under channel mode.
When you want to operate Menu functions, input the password you set, then switch to
frequency mode.
NOTE:
•
When the transceiver is on dual standby (TDR appears), the frequency that is
displayed by the arrowhead is master (= primary status) frequency, the other one is
vice (= secondary status) frequency. When vice frequency receives, the LCD displays
" S ". In dual standby, the master frequency is used for transmission; the vice
frequency only can be used for receiving.
•
Master Frequency Setting: In dual standby, press A/B key to select the master
frequency.
