Temporarily install, with light pressure, the silver target on the side of the handset earphone
adjacent to the TRI-804. Adjust the position of the TRI-804 housing (raise, lower or slide) so the
apertures in the housing are aligned with the target on the handset so when ON-HOOK the LED is
out and OFF-HOOK the LED is ON. Adjust the target position if necessary. When aligned, press
the adhesive pads of the target and the housing firmly against the phone for permanent location.
With the handset ON-HOOK, the LED is out, the handset is muted and no audio goes to the
recorder. With the handset OFF-HOOK, the LED is lit, the handset operates normally and audio
goes to the recorder. If these conditions are met, the unit is properly aligned and correctly
installed.
