TROUBLESHOOTING
4.3
The following section will describe the troubleshooting procedure for several common
issues. If these sections do not cover your particular issue, it is recommended that the
chamber wiring be disconnected from the communicator and the check-out procedures in
section 5.1 be conducted. If the chamber communicator passes the check-out procedures
then the issue is most likely in the chamber wiring.
4.3.1
LOW-BATTERY INDICATION
The BATTERY CONDITION INDICATOR indicates the battery level or state-of-
charge by monitoring the battery voltage. The voltage has to be 9 Volts or greater
for the 2810E-02 communicator to operate. If the BATTERY CONDITION
INDICATOR indicates a low (blinking LED) or bad (off LED) after charging, then
either the battery is bad and needs to be replaced or the charger has
malfunctioned.
Before replacing either battery, the battery connections should be checked by
opening the battery compartment and inspecting the wires. Verify that the wires
are firmly attached and that the RED wire is connected to the positive terminal and
that the BLACK wire is connected to the negative terminal.
4.3.2
UNIT NOT OPERATING
The most common reason that a chamber communicator appears to be dead when
the POWER SWITCH and SPEAKER SWITCH are turned on, is a bad or loose
battery. Check the battery per section 5.3.1. If the battery is good, then disconnect
any chamber wiring and perform the communicator check out procedure per
section 5.1.
If the battery and battery connections appear good and the communicator fails the
check-out procedure, then remove the screws holding the front panel. Lift the front
panel up carefully as the panel components are connected to a Printed Circuit
Assembly (PCA) by a wire harness. Verify that the connectors on the PCA are
firmly seated. Check that the wire harnesses are soldered to the various
connectors, controls, and speaker. There should be no loose wires in the system.
Remove the fuse from the PCA. It is marked FH1 and is a cylindrical component.
Verify that the fuse is good by checking the continuity with a multi-meter. If the fuse
is open, replace with a same type: 3.15 Amp, 250V, Fast Acting. Close the front
panel; re-install the screws and re-test the communicator. If the communicator still
appears dead, contact Amron per section 2.2 for further assistance.
4.3.3
LOW VOLUME
Check the volume control settings and adjust if necessary. Check the chamber
connections and verify that the chamber and operator are connected as intended.
Verify the wires and connectors are clean and tight. Check the BATTERY
CONDITION INDICATOR and test the battery if necessary. If the problem persists,
disconnect the chamber wiring and perform the communicator check out
procedure per section 5.1. If the communicator fails the check-out procedure,
contact Amron per section 2.2 for further assistance.
