Auxiliary Headset Operation (701-904 only)
The auxiliary headset allows the user to make page announcements and conduct party-line conversations
hands-free from up to 30 feet from the station, while providing noise reduction for hearing protection.
When an auxiliary headset/cable assembly is plugged into the auxiliary jack, a party-line connection is
automatically established (the same as lifting the handset).
NOTES:
1. Allowing the auxiliary headset to remain plugged in for a long period of time may disable party-line
communication. This condition is controlled by the off-hook time-out setting, which can be
programmed for 1 to 25 minutes in 1-minute steps (the factory default is 8 minutes) or it can be
disabled. This feature ensures that a station unintentionally left connected to a party line will not
induce unwanted background noise onto the party line. If party-line communication is disabled,
unplug the auxiliary headset, then plug it back in.
2. The auxiliary headset has priority over the handset. When the user lifts the handset from the cradle
while the auxiliary headset is in use, the handset’s microphone and page switch are disabled, but the
handset receiver remains active.
3. This application requires the GAI-Tronics Model 10401-201 Headset/Microphone Assembly and
Model 10416-103 Extension Cable.
Page Announcement
To make a page announcement for a party-line conversation, perform the following steps:

Adjustments
The User Adjustment Control is located beneath the GAI-Tronics nameplate on the front panel. Refer to
Figure 1. It is used to make all user adjustments normally required for installation. Loosen the two
screws on the GAI-Tronics nameplate and rotate it counterclockwise to access the adjustment hole. Make
adjustments by inserting a 1/8-inch flat blade screwdriver through the access hole and into the
potentiometer located directly behind the hole.
The User Adjustment Control potentiometer can be used to make three separate adjustments:
•
the minimum Speaker Amplifier output level setting
•
the Offset Amplifier level (difference between the ambient noise and the amplifier output levels)
•
the VLC (volume level control) adjustment
(sets a preset speaker level to override the normal volume control setting).
Minimum Level Adjustment
To set the minimum amplifier output level, insert the 1/8-inch flat blade screwdriver into the User
Adjustment Control and set it fully counterclockwise. Listen for a single beep from the speaker
indicating the speaker amplifier is in the Minimum Level Adjustment mode. A continuous tone should be
heard after the beep tone. (See note below).
This test tone is used as a reference to adjust the speaker amplifier output level to the desired volume.
Turn the adjustment pot clockwise for the desired output. The test tone automatically shuts off 5 seconds
after the last adjustment. The factory default setting for minimum level is 4.0 watts nominal.
NOTE: If the page line is in use immediately after the beep tone, the page signal should be used to make
the minimum level adjustment. If the page line is inactive following the beep tone, a continuous tone is
activated to make the minimum level adjustment. After the tone is activated, all page line activity is
ignored until completion of the adjustment.
Offset Level Adjustment
The Offset Level allows the output of the SmartVolume™ speaker amplifier to maintain a set difference
or “offset” between the ambient noise level and the speaker output level. Turn the User Adjustment
Control fully clockwise and listen for the two beep tones indicating that the station is in the Offset
Adjustment mode. A continuous tone should be heard from the station speaker. Turn the adjustment pot
counterclockwise to the desired output level.
NOTE: If the page line is in use immediately after the two beep tones are heard, the page signal should be
used to make the offset level adjustment. If the page line is inactive immediately following the beep
tones, a continuous tone is activated to make the minimum level adjustment. After the tone is activated,
all page line activity is ignored until completion of the adjustment

PAGE 10 of 16
42004-658L2D
VLC Level Adjustment
When activated, the VLC overrides the normal volume control setting allowing the amplifier level to
change to a preset level during an emergency page. The factory default setting for the VLC Level is 10%
of maximum power (nominally 1.2 watts).
NOTE: The system must be equipped with a SmartSeries MCU (Master Control Unit) to activate the
VLC function.
To adjust the VLC Level:
1. Force the station into the VLC mode by having someone execute a page from a station programmed
by the MCU to activate the VLC function.
2. During the page, turn the User Adjustment Control fully counterclockwise, and listen for two beep
tones through the page speaker indicating the VLC Adjustment mode has been activated.
3. After the two beep tones, turn the User Adjustment Control to the desired speaker level using the live
paging signal to adjust the level. The station automatically exits the VLC Adjustment mode and
reverts to normal operation 5 seconds after the last pot adjustment.

Internal Adjustments
Although they typically require no adjustments, the following volume levels can be set internally:
Sidetone Volume and Handset Receiver Volume
To make an adjustment it is necessary to remove the assembly from its enclosure and make a temporary
connection between the assembly and the enclosure. Refer to Figure 2 for the reference numbers and
locations of the adjustment controls. Turn a control clockwise to increase the volume or threshold; turn it
counterclockwise to decrease the volume or threshold. Use a small flat-blade screwdriver with an
insulated shaft to make adjustments.
To access the controls, perform the following steps:
1. Loosen the 4 screws that secure the front panel.
2. Remove the assembly from the enclosure. If the enclosure is equipped with an optional EOL Module
or SmartSeries station RTU, be careful to not disconnect the ribbon cable on J2 of the Speaker
Amp/Power Supply PCBA.
3. Connect the assembly to the enclosure using a Model 10440-002 Maintenance Cable between P1 on
the assembly and J1 on the enclosure.
4. Locate and adjust the control on the appropriate PCBA.
5. When you are finished with the adjustment:
a) Disconnect the Model 10440-002 Maintenance Cable.
b) Insert the assembly into the enclosure.
c) Tighten the 4 screws.
Handset Receiver Volume
Use the control labeled RCVR VOL (Ref. 7, on the Handset/FSK/µP PCBA) to adjust to the desired level
the handset receiver volume for voice signals from a party line.
Sidetone Volume
The control labeled SIDETONE (Ref. 4, on the Handset/FSK/µP PCBA) adjusts the handset/headset
sidetone.

Troubleshooting
The following table lists some hints to aid technicians in troubleshooting.
Problem
Any problem with
station performance
Possible Solution
Remove the assembly from the enclosure and examine it carefully for obvious
faults such as unconnected plugs, loose connections where the wires from the
handset and hookswitch connect to the Handset/FSK/µP PCBA, and so on.
Determine whether the fault is in the assembly, or in the system, by plugging
in a known good spare assembly (set to the same address as the assembly
removed). If the fault is in the assembly, remove it for repair.
NOTE: When replacing the assembly, perform the following steps:
1. Set the address on the new assembly to 0,3.
2. Plug the assembly into the enclosure.
3. After about 10 seconds, remove the assembly. The station is now set up
to request a download of configuration variables from the MCU.
4. Set the unit to the correct address. Set the address to 04 for conventional
Page/Party® operation or consult the ADVANCE system manual for
address assignment information.
5. Plug the assembly back into the enclosure. The station initiates a
configuration download request (ADVANCE systems only). The time
required to complete the download depends upon system configuration
and system activity, but several seconds is typical.

when speaking
•
If the problem affects all stations, the line may not be terminated
correctly, may have loose connections, or a short to ground. Line balance
connections are critical.
•
If the problem affects only this assembly, the problem may be with its
sidetone setting. Contact the GAI-Tronics Field Service Department.
•
Check within the enclosure for a purple wire on terminal 7: this is the
default setting for local speaker mute. If the wire is on terminal 8, then
the speaker is unmuted and may be causing feedback. Connect the wire
to terminal 7.
•
An adjacent speaker could be causing feedback. If an adjacent speaker is
the source of the feedback, adjust the orientation of the speaker so that it
is not aimed directly at the station. As a last resort, enable the mutual
muting function of the station. This is done by interconnecting terminal 7
of the two stations with the spare orange wire in the system cable (if this
wire is available).

Cause and Effect
Cause—The watchdog timer has forced the
processor to reset. This occurs when the reset
pins (J2) on the Handset/FSK/µP PCBA are
temporarily shorted or when the watchdog
timer does not receive regular status pulses
from U4 on the Handset/FSK/µP PCBA.
Possible Solution
•
Verify that the reset pins
2 and 3 (J2) on the
Handset/FSK/µP PCBA
are not shorted.

Effect—The processor maintains a count of
the number of resets. If the station is powered
down, the count restarts at zero. The station
still amplifies incoming pages. For the fourth
and subsequent resets, the count is zero.
Cause—The station has been in page mode
longer than the configured page limit.
Effect—Station page is cut off. When the
pressbar is released, a restore message is sent
to the MCU. The station then resumes normal
operation.
•
•
Stuck Contact on

communication is resumed, the LED
extinguishes and a restore message is sent to
the MCU.
•
Replace the station
assembly.
Cause—This message is output by the MCU
when it loses communication with the station.
This may occur if there is a fault in the page

is some fatal malfunction within the station.
Effect—The MCU continues to attempt
communication with the station. When
communication is resumed, a restore message
is sent to the MCU.
