Changing frequency channel
If you are experiencing problems with the range or reliability this may be due to poor reader positioning, adjacent
interfering 125 kHz or 2.4 GHz equipment, e.g. an adjacent wireless PC network. Please refer to the 'Before you
install' information regarding unit locations. If you are still unable to improve the system performance then you
may try an alternative 2.4 GHz channel using Switch 1. Power cycle the unit after any changes.
The system has 16 channels available. (Unless a keycard ixed channel is selected) The unit is set to channel 4
as this frequency is normally clear of other device transmissions. This can be changed using a small lat blade
screwdriver. Take care not to contact the circuit board with the screwdriver blade as this may damage components.

Enrolling hand free keyfobs and keycards
Switch SW2 is used to select the ixed channels used by the two keycard buttons. Select either switch 1 or 2
to set which keycard button the interface will respond to.
SW2 - Keycard button 1 and 2 ixed channels - If either switch 1 (Channel 26) or switch 2 (Channel 11) is set,
the rotary frequency switch is disabled. If both switches are selected, the interface will not operate.
The unit must be power cycled if the switch position is changed, to activate the new setting.

Hands free keyfobs
These tokens should be assigned to users as per standard keyfobs. They will then operate with normal P series
readers or via the hand free interface when in range.
Hands free keycards
These should irst be assigned as per the hands free keyfob.
To enable the buttons, the keycard must irst be presented to the P series reader and then used in hands free
mode. The keycard stores the details of this interface and can then activate the door using a button.
It can also be used in normal hands free mode and also in local passive mode with other standard readers.
