Troubleshooting the IDR1000A DC Remote Desk Set
The following is a list of potential problems you may encounter and possible solutions.
Problem Possible Solution
General problems. Ensure that there is a valid circuit line path from the desk set to the dc remote
adapter.
Ensure that the private circuit is balanced by making sure neither side of the
telephone line is grounded.
Check for a blown fuse and ensure that the desk set is connected to a dc power
source.
The desk set will not
cause the dc remote
adapter to key the radio. Ensure that the proper dc current magnitude for the dc adapter to key the radio
is programmed into the desk set. Refer to the dc adapter service manual.
Ensure that the desk set’s output level is set properly, and that the DCLOTL is
set in a range of 5 mA to 14 mA into the telephone line.
RX audio is low or
distorted. Ensure that the dc adapter is wired correctly, including the RX audio pair.
Audio quality is limited by the quality of the private radio circuit or leased
lines between the station radio equipment and the remote dispatch point(s). In
some cases, equalization of the lines or line conditioning may be required to
ensure a reasonably flat line.
Correct the desk set’s receive audio pot 3 setting:

Too high sensitivity overdrives the unit and results in distorted receive
audio.

A setting that is too low results in low speaker or handset audio.
If the internal speaker audio is adequate and only the earpiece is low, check
the handset level pot 5 setting. See the “Settings and Adjustments” section in
the “Operations” section of this manual.
