buttons, change modes etc.
If you prefer your meter not to make these sounds, you can turn them off here.
Figure 21: Sound Setting
❢ Note: Turning the sound off here does not affect the sounding of some
alarms and warnings, including the Speed Alarms.
5.5.3 Automatic Turn Off Feature
The MR400 has an optional facility designed to prevent excessive drain on
your vehicle’s battery if you accidentally leave the meter in FOR HIRE mode
for an extended period of time.
With the feature turned ‘ON’, the meter will time out after 2 hours if left in
FOR HIRE mode with no signal received from the pulse input and no button
operations. The meter will warn you for 1 minute before actually switching off
to give you the opportunity to cancel the facility.
