PROGRAMMING OWNER'S INFORMATION
The information accessible by the
to allow information unique to the radio transceiver or its location to be stored in the
EEPROM. Normally, this field is left blank on units as shipped from MDS.
To program these fields, proceed according to the following directions:
1. Open the diagnostics channel.
2. Type in

entered using the above steps.
5. Close the diagnostics channel.
PASSWORD PROTECTION
If password protection of programmed information (frequency, owner's name and message,
etc.) is used, the PASS command followed by the correct four-character password must be
entered before the transceiver programming can be changed. Without the proper password,
the programmed information and diagnostic data can only be reviewed, and no access to the
programming commands is possible.
For more information on password protection, contact the MDS Systems Engineering.
DIAGNOSTIC EVALUATION
Using the diagnostic commands, a technician can read important voltages and levels with the
HHT. These values are updated once every second, allowing adjustment of the levels without
the need for invoking the command each time a control is moved. Below is a list of the
commands, with the display to be expected after typing the command followed by an
keystroke.
------------- Supply voltage supplied to transceiver.

------------- Main regulator voltage.
