Maintenance
External Adjustment
The Model 723-801 SmartSeries®Remote Amplifier contains one external adjustment, the User Level
Adjustment. This adjustment is located behind the GAI-Tronics nameplate on the front panel. The User
Level Adjustment controls the speaker output level as described below:
Minimum Level setting—This setting controls the minimum speaker output level. Using a small flat-
blade screwdriver with an insulated shaft at least 4 inches long, adjust the Minimum Level as follows:
1. Loosen (do not remove) the 2 screws that secure the GAI-Tronics nameplate. Pivot the nameplate
counterclockwise, exposing the access hole. A guide behind the access hole helps direct the
screwdriver to the USER ADJ control.
2. To initiate the Minimum Level Setting Mode, turn the USER ADJ fully counterclockwise until a
single beep is broadcast over the station’s speaker. If a page is in progress, it will broadcast over the
station’s speaker, otherwise, a test tone is broadcast.
3. Turn the USER ADJ clockwise to the desired minimum speaker level and remove the screwdriver.
The amplifier can be set from minimum to full output (12 watts into 8 ohms) in 100 discrete steps, or
to no output.
Note: The station remains in the Minimum Level adjustment mode for as long as USER ADJ is
varying. After USER ADJ has remained stable for five seconds, the station returns to its normal
operating mode. At this point, rotate the USER ADJ to mid-range.
4. When you are done with the adjustment, pivot the nameplate clockwise into position, then tighten the
2 screws.
Offset Level setting— This setting determines the speaker output level above ambient noise. The
amplifier automatically adjusts the speaker output level to be equal to the measured ambient noise level
plus the preset Offset Level. This produces page announcements at a preset level above the ambient
noise. For pages to be intelligible, the speaker output level should be set 6 to 10 dB louder than the
ambient noise.
Note: If the combination of the ambient noise level plus the preset Offset Level are less then the
minimum level, the page is broadcast at the minimum level. To adjust the Offset Level, perform the
following steps:
1. Use a small flat-blade screwdriver with an insulated shaft at least 4 inches long to make adjustments.
Loosen (do not remove) the 2 screws that secure the GAI-Tronics nameplate.
2. Pivot the nameplate counterclockwise, exposing the access hole. A guide behind the access hole
helps direct the screwdriver to the USER ADJ control.
3. To initiate the Offset Level Setting Mode, turn the USER ADJ fully clockwise until two beeps are
broadcast over the station’s speaker. If a page is in progress, it will broadcast over the station’s
speaker, otherwise, a test tone is broadcast.
4. Turn the USER ADJ counterclockwise until the desired speaker level above ambient is reached and
remove the screwdriver. The Offset Level can be set from 0 dB (the speaker output level is the same
as the ambient level) to 49 dB. Note: The station remains in the Offset Level adjustment mode for as
long as USER ADJ is varying. After USER ADJ has remained stable for five seconds, the station
returns to its normal operating mode. At this point, rotate the USER ADJ to mid-range.
5. When complete, pivot the nameplate clockwise into position, then tighten the 2 screws.

VLC Level setting— This setting controls the speaker output level when Page Priority VLC is enabled.
The amplifier automatically adjusts the speaker output level to the preset VLC Level whenever the
incoming page matches the configured Page Priority VLC setting (i.e. the Page Priority and inequality
conditions are met). To adjust the VLC Level, perform the following steps:
1. Use a small flat-blade screwdriver with an insulated shaft at least 4 inches long to make adjustments.
Loosen (do not remove) the 2 screws that secure the nameplate.
2. Pivot the nameplate counterclockwise, exposing the access hole. A guide behind the access hole
helps direct the screwdriver to the USER ADJ control.
3. Have an assistant page from a station that meets the required Page Priority VLC settings.
4. To initiate the VLC Level Setting Mode, turn the USER ADJ fully counterclockwise until two beeps
are broadcast over the station’s speaker.
5. Turn the USER ADJ clockwise to the desired speaker volume level. The amplifier can be set from
minimum to full output (12 watts into 8 ohms) in 100 discrete steps, or to no output.
Note: The station remains in the VLC Level adjustment mode for as long as USER ADJ is varying.
After USER ADJ has remained stable for five seconds, the station returns to its normal operating
mode. At this point, rotate the USER ADJ to mid-range.
6. When complete, pivot the nameplate clockwise into position, then tighten the 2 screws.

Troubleshooting
Problem Possible Solution
There is any problem with
station performance. 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 Amplifier
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 03.
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 MCU.
4. Set the address to the correct address.
5. Plug the assembly back into the enclosure. The station initiates a
configuration download request. The time required to complete the
download depends upon system configuration and system activity,
but several seconds is typical.
Speaker volume needs
adjustment. Use the USER ADJ control to adjust the Minimum Level, Offset Level,
or VLC Level (as appropriate). Refer to the Adjustments section of this
document.
Incoming handset speech
level needs adjustment. Use the RCVR VOL control to adjust the handset receiver volume. Refer
to the Adjustments section of this document.
Outgoing speech level is
too low for other users. Use the XMIT LEVEL control to adjust the audio transmit level. Refer to
the Adjustments section of this document.
Crosstalk occurs. Likely to be external to the assembly and related to system cable faults.
Acoustic feedback or
speech distortion during
page or party operation or
the user hears himself
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 GAI-Tronics’ Field Service Department.
Feedback during page
only. •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 un-muted 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).

When the assembly is in an ADVANCE system, faults may be automatically detected, transmitted to the
MCU in data messages, and printed out. Fault messages and possible solutions for their causes are
described in the table below.
Fault Message Cause and Effect Possible Solution
Watch-Dog timer
Processor has
Reset xd times
(Where xis the
decimal number of
times the
watchdog timer
has reset the
processor.)
Cause—The watchdog timer has forced the
processor to reset. This occurs when the reset
pins (J4) on the Base-24 PCBA are temporarily
shorted or when the watchdog timer does not
receive regular status pulses from U2 on the Base-
24 PCBA.
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. On the fourth and
subsequent resets, the xvalue in the error message
is 0.
•Verify that the reset pins
(J4) on the Base-24
PCBA are not shorted.
•Replace the Base-24
PCBA.
Stuck Contact on
Polled Device
Paging Pressbar
Depressed
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.
•Verify that the handset
pressbar is not stuck.
•Replace the Handset
Amplifier PCBA.
•Replace the Base-24
PCBA.
Stuck Contact on
Polled Device
Handset Off-hook
Cause—The station has been in the off-hook state
longer than the configured time limit.
Effect—Station handset operation is cut off.
When the station is returned to the on-hook state,
a restore message is sent to the MCU. The station
then resumes normal operation.
•Verify that the handset is
not off-hook.
•Replace the Handset
Amplifier PCBA.
•Replace the Base-24
PCBA.
Supervised Audio
Path
Handset
Cause—The station failed its internal health
check of the Handset Amplifier PCBA.
Effect—The station disables the handset amplifier
health-check function after the first failure. This
is a non-restorable fault.
•Replace the Handset
Amplifier PCBA.
•Replace the Base-24
PCBA.
Supervised Audio
Path
Page Amp
Cause—The station failed its internal speaker
amplifier health check.
Effect—The station disables the speaker amplifier
health-check function after the first failure. This
is a non-restorable fault.
•Replace the Base-24

Fault Message Cause and Effect Possible Solution
Supervised Audio
Path
Speaker Voice
Coil
Cause—The station is detecting no ambient noise
at the speaker or is detecting an ambient noise
lower than the configured failure threshold. This
may occur if there is a fault in the speaker wire or
a fault at the voice coil. This also may occur if
the ambient noise at the speaker is too low, as is
the case in a quiet room.
Effect—The station continues measuring speaker
ambient noise. When acceptable noise levels are
subsequently measured, a restore message is sent
to the MCU.
•Verify that the speaker
wire is connected and
intact.
•Verify that the voice coil
is connected and intact.
•Verify that the Offset
Level adjustment is set
correctly.
•Replace the Base-24
PCBA.
Polled device 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 line,
if the station is powered-down, or if there is some
fatal malfunction within the station.
Effect—The MCU continues to attempt
communication with the station. A restore
message is output when communication is
resumed.
•Verify that the page line
is connected and intact.
•Verify that the station is
installed correctly.
•Replace the Base-24
PCBA.
Polled End-of-line
device Cause—This message is the same as the “Polled
device” fault, except that the affected station has
been defined as an end-of-line station in the MCU
configuration.
Effect—When this fault occurs, the red EOL FLT
LED on the Page/Party®Interface (PPI) bezel
lights. The LED extinguishes and a restore
message is output when communication with the
station is resumed.
•Verify that the page line
is connected and intact.
•Verify that the station is
installed correctly.
•Replace the station
assembly.
