T6M SERIES MOBILE SERVICE MANUAL – SM/16/1.0
5.5 Key beeps.
The mobile may produce a single beep whenever a button is pressed. This option is
selected during programming. The volume is the same as warning sounds and is set when
the mobile is programmed.
5.6 Display Blanking
Display blanking is an option that can be enabled when the mobile is programmed. The
display blanking time is programmable.
When display blanking is enabled, the normal frequency display is replaced by a flashing bar,
if the mobile is not used for the display blanking time.
A blanked display is reinstated by pressing any button, including the on / off button, or by
pressing the microphone PTT button. It is recommended that the volume buttons be used as
this reinstates the display without altering any settings.
Display blanking only operates when the mobile is receiving in normal mode or in priority
mode.
