button. Normal operation should occur. If it does not, perform a "hard
reset" described in step 2.
• Step 2 – "Hard Reset": Again using a bent paperclip, press and hold
the reset button. While the button is held down, remove the DC power
cable from the repeater, and then plug the cable back in. Continue to
hold the reset button for approximately 45 seconds, and then release
it.
This procedure completely resets the repeater's microprocessor
and other software settings. Normal operation should occur. Note: If
the remote alarming option is installed, this "hard reset" will reset all
user names and passwords back to the factory default settings
described in the Operator's Manual.
Other troubleshooting procedures are described in the table below.
