5 Operating Instructions
5.1 Introduction
To set up the TR-810 transceiver unit, various parameters can be selected from the front
panel. This section show how this is done and the range of all parameters.
Since the transceiver unit contains no manual tuning points or switches, all parameters can
in principal be set from the front panel, however in some rare occasions, most parameters
should be left at their default (factory preset) values.
There are 2 user levels that can be selected to limit the user access to certain parameters.
These user levels are:
• Restricted Limits front panel operation to select preset channels and adjust
audio output levels, turn the squelch on/off and change the display
appearance. Use this level when the radio is used in cases where the
user should be restricted to use preset channels only (0 – 63).
• Operation Same as restricted, but in addition the local user has full access to
change and store channel names, the squelch operating level and
frequencies.
• Technician This level gives the local user access to the most used installation
specific parameters (line levels, output power, etc.) and should be
used only for installation or maintenance of the transceiver.
To access this level a code must be typed.
In the following section, these symbols and abbreviations are used to explain navigation in
menus / setting of values:
• Scroll/Select switch =
• Navigation button A (top left button) =
• Navigation button B (middle left button) =
• Navigation button C (on/off button) =
