Audio Recording:
We record and time-stamp all repeater audio. So if you have a problem with interference or unauthorized/improper use please make a note of the date and time. If you have a problem being recorded, don't use the repeater.

Battery Operation (loss of utility power):
Our system is a "loaded battery" system and is on battery 100% of the time. When we have utility power, the charger just supplies power as it is used. Upon loss of utility power, the courtesy tone is changed from one short beep two one short beep followed by two short low-frequency beeps. The controller will announce "Repeater on Battery Power" when the power is lost and every 30 minutes after that. 
Have a look at the battery install!

Time Out Timer:
The time-out timer is set for three minutes. If a user continuously keys the repeater for three minutes, the controller will state "Repeater Time Out" this message will be heard by all users, except the user causing the situation. As soon as the repeater detects a drop in the carrier, the controller will reset and be ready for normal operation again. It is NOT necessary to allow the repeater to drop the carrier, the TOT is reset every time the user un-keys, and the courtesy tone is transmitted.

To access the repeater, you must use a TX tone of 88.5. The repeater also transmits a tone of 88.5 if you wish to set your radio for decoding. We recommend this since several other repeaters use the same pair and you will receive them also.

Use of the Repeater for an Event or Net:
Please contact the club president for information on the use of the repeater for an event or net.

Known Issues:
During the loss of commercial power, users will notice fan noise in the audio.  this is a known problem and we have not yet resolved the problem.
