MISCELLANEOUS TECHNICAL NOTES |
Note: Transmit level adjustment, this can be made by looking under the Phone Link for a screw potentiometer. Turning the screw clockwise will increase transmit level and turning the screw counterclockwise will decrease transmit level. This should be done if you are experiencing errors receiving data or the remote receiving data from the Phone Link. Diagram not available. |
