If a ACCSI with GPS receiver is connected to the ACC501, it is powered off by default. “GPS
module is switched off” will be displayed in the fields for longitude and latitude:
Please note:
To save power the GPS module should only be switched on when needed.
After switching the GPS module on by pressing key 1, at first the message “Waiting for GPS
NMEA data… “ is displayed.
Once the GPS antenna has established link with enough satellites to emit valid data, the
fields for longitude and latitude will be filled with values and refreshed permanently.
Using the command “8 – Edit UTC Offset”, the GPS time should be adjusted to the local time
zone. The offset can be adjusted in steps of 5 minutes, as some countries have an offset that
is not full hours. The offset is displayed on the top left (in the graphic above: UTC – 14:45)
