Settings and Adjustments

Speaker Volume Adjustment

The speaker volume control on the rear of the unit adjusts the volume level of the internal speaker.

Clockwise rotation will increase the volume and counterclockwise rotation will decrease the volume.

: The handset must be on-hook to adjust the speaker volume because the speaker is muted when the

OTE

handset is off-hook.

Sonalert Volume Adjustment

The sonalert volume control on the rear of the unit adjusts the volume level of the sonalert (sounder).

Clockwise rotation will increase the volume and counterclockwise rotation will decrease the volume.

Opening the Enclosure

Carefully flip over the unit. Remove the four screws from the bottom of the plastic enclosure. Open the

access panel by removing the bottom enclosure to the right of the unit. Be careful not to disconnect any

cables.

Jumper Settings

External Audio Input

Jumper P6 on No. 69447-xxx PCBA must be set to match the input level of the external audio source

connected to the audio accessory port. Place P6 in the HI position (default setting) for a line level

(0.775 Vrms) audio signal. Place P6 in the LO position for microphone level (3 mVrms) audio signals.

Refer to Figure 6 for jumper location.

TX/RX Data

Jumper P9 on No. 69447-xxx PCBA provides a ground reference to the access panel data line. A similar

jumper is located on the Access Panel Interface (API) card in the system control cabinet. The data line

must be ground referenced on one side of the communication link but not both. Place P9 in the GND

position to create a ground reference. Place P9 in the FLOAT position (default) to remove the ground

reference. Refer to Figure 6 for jumper location.
