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:

 Minimum speaker amplifier output level setting

 Offset amplifier level (difference between the ambient noise and the amplifier output levels) adjustment

 VLC (Volume Level Control) adjustment (sets a preset speaker level to override the normal volume control setting)

Minimum Speaker Amplifier Output Level Setting

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.

N

OTE

: 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.

N

OTE

: 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 f:\standard ioms - current release\42004 instr. manuals\42004-685l2d.doc

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 four 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 four screws.

Handset Receiver Volume

Use the control labeled RCVR

VOL

(Ref. 7, on the Handset/FSK/

P 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/

P PCBA) adjusts the handset/headset sidetone. f:\standard ioms - current release\42004 instr. manuals\42004-685l2d.doc

P

AGE

11 of 15

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/FSK/

P 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.

N

OTE

: 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 0, 4 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.

Use the USER

ADJ

control to adjust the Minimum Level, Offset Level, or

VLC Level (as appropriate). Refer to the “Adjustments” section on page 8.

Use the R

CVR

V

OL control to adjust the handset receiver volume. Refer to the

“Adjustments” section of this document.

Feedback during page only

Crosstalk

 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/

P PCBA are temporarily shorted or when the watchdog timer does not receive regular status pulses from U4 on the Handset/FSK/

P PCBA.

Possible Solution

 Verify that the reset pins

2 and 3 (J2) on the

Handset/FSK/

P PCBA are not shorted.

 Replace the

Handset/FSK/

P 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. 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.

Cause—The station has been in the off-hook state longer than the configured time limit.

Effect—Station handset/headset 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.

Cause—The station failed its internal health check of the Handset/FSK/ failure.

Effect—The station disables the handset amplifier health-check function after the first

Cause—The station failed its internal speaker amplifier health check.

Effect—The station disables the speaker amplifier health-check function after the first failure.

 Verify that neither the handset pressbar nor the headset page switch is stuck.

 Replace the

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.

Cause and Effect Possible Solution

 Verify that the speaker wire is connected and intact.

 Verify that the voice coil is connected and intact.

 Replace the Speaker

Amp/Power Supply

PCBA.

 Replace Handset/FSK/P

PCBA.

Effect—The station continues measuring speaker ambient noise. When acceptable noise levels are subsequently measured, a restore message is sent to the MCU.

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. When communication is resumed, a restore message is sent to the MCU.

 Verify that the page line is connected and intact.

 Verify that the station is installed correctly.

 Replace the

Handset/FSK/

P PCBA.

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 PPI bezel lights. When communication is resumed, the LED extinguishes and a restore message is sent to the MCU.

 Verify that the page line is connected and intact.

 Verify that the station is installed correctly.

 Replace the station assembly. f:\standard ioms - current release\42004 instr. manuals\42004-685l2d.doc

Equipment.

GAI-Tronics warrants for a period of one (1) year from the date of shipment, that any

GAI-Tronics equipment supplied hereunder shall be free of defects in material and workmanship, shall comply with the then-current product specifications and product literature, and if applicable, shall be fit for the purpose specified in the agreed-upon quotation or proposal document. If (a) Seller’s goods prove to be defective in workmanship and/or material under normal and proper usage, or unfit for the purpose specified and agreed upon, and (b) Buyer’s claim is made within the warranty period set forth above,

Buyer may return such goods to GAI-Tronics’ nearest depot repair facility, freight prepaid, at which time they will be repaired or replaced, at Seller’s option, without charge to Buyer. Repair or replacement shall be Buyer’s sole and exclusive remedy. The warranty period on any repaired or replacement equipment shall be the greater of the ninety (90) day repair warranty or one (1) year from the date the original equipment was shipped. In no event shall GAI-Tronics warranty obligations with respect to equipment exceed 100% of the total cost of the equipment supplied hereunder. Buyer may also be entitled to the manufacturer’s warranty on any third-party goods supplied by GAI-Tronics hereunder. The applicability of any such third-party warranty will be determined by GAI-Tronics.

Services.

Any services GAI-Tronics provides hereunder, whether directly or through subcontractors, shall be performed in accordance with the standard of care with which such services are normally provided in the industry. If the services fail to meet the applicable industry standard, GAI-Tronics will re-perform such services at no cost to buyer to correct said deficiency to Company's satisfaction provided any and all issues are identified prior to the demobilization of the Contractor’s personnel from the work site. Re-performance of services shall be Buyer’s sole and exclusive remedy, and in no event shall GAI-

Tronics warranty obligations with respect to services exceed 100% of the total cost of the services provided hereunder.

Warranty Periods.

Every claim by Buyer alleging a defect in the goods and/or services provided hereunder shall be deemed waived unless such claim is made in writing within the applicable warranty periods as set forth above. Provided, however, that if the defect complained of is latent and not discoverable within the above warranty periods, every claim arising on account of such latent defect shall be deemed waived unless it is made in writing within a reasonable time after such latent defect is or should have been discovered by Buyer.

Limitations / Exclusions.

The warranties herein shall not apply to, and GAI-Tronics shall not be responsible for, any damage to the goods or failure of the services supplied hereunder, to the extent caused by Buyer’s neglect, failure to follow operational and maintenance procedures provided with the equipment, or the use of technicians not specifically authorized by GAI-Tronics to maintain or service the equipment. THE WARRANTIES AND REMEDIES CONTAINED HEREIN ARE IN LIEU OF AND

EXCLUDE ALL OTHER WARRANTIES AND REMEDIES, WHETHER EXPRESS OR IMPLIED BY

OPERATION OF LAW OR OTHERWISE, INCLUDING ANY WARRANTIES OF
