SWITCH THE FENCE ON/OFF
To switch the fence On or Off, enter your four digit PIN followed by the #key.
If the red ON light is lit or flashing, the fence is energized.
• Don’t pause for more than 5 seconds while entering the digits, or the control panel
will reject your PIN number.
• If you make a mistake while entering your PIN, press the #key and start again.
• The default master (User # 1) PIN is 1 2 3 4.
The default user (User # 2) PIN is 5 5 5 5.
AFTER AN ALARM OCCURS
Enter your PIN and press the #key. This will silence the buzzer and siren.
It will switch the fence off. One of the ALARM lights will flash or stay lit to indicate the
source of the alarm. A flashing indicator illustrates that the fault condition persists.
A permanently lit indicator notifies the user that the fault no longer exists.
CHANGE THE VOLTAGE
ON THE FENCE
Enter your PIN and press the *key, enter the digit 3, then press the #key.
When the fence is on and in low voltage mode, the red ON light will flash.
The red ON light will stay permanently lit if the fence is in high voltage mode.
Use the low voltage mode when children are in the fence vicinity.
BYPASS THE FENCE ALARM
Enter your PIN and press the *key, enter the digit 1, then press the #key.
