Remove the existing handset and cord from the voice terminal.
Place the M6500Pv5 so it’s handset plug will reach the handset jack on the voice terminal. Adhesive strips are provided for attaching the module to the voice terminal. Insert the pigtail plug from the M5600Pv5 to the handset jack on the voice terminal.
Connect the handset cord to the modular handset jack on the M6500Pv5.
The audio output is on pair 1 of the RJ-48C jack. It connects to a high impedance recorder input. Use option switch 1 to set the output level.
Connect the AC adapter to the POWER jack on the rear of the M6500Pv5.
The M6500Pv5 produces a beep tone audible to both parties for recording notification. The beep tone is a 200ms 1390Hz tone burst every 12-15 seconds. The beep tone may be turned on or off with switch 2.
Set option switch 3 for the type of trigger input: off for a positive trigger or on for a negative trigger. If you are not using this feature, be sure to leave it in the off (up) position or the beep tone will not function.
Switch-hook is a logical output from the voice terminal which follows the condition of the handset (on hook or off hook). It may be positive logic (ground on hook, +5v off hook) or negative logic (+5v on hook, ground off hook). The MA18 trigger lead supplied with the M6500Pv5 must be soldered to the point in the voice terminal that provides this trigger.
Contact Avaya Communications (1-800-225-6907) to obtain a sketch indicating the connection point for the specific voice terminal you are using.
Route the bare end of the trigger lead into the voice terminal base. Solder the lead to the switch-hook logic connection point; this point will be indicated on the sketch for your specific voice terminal.
A low wattage, pencil tipped soldering iron, and small diameter multicore solder (.028 or .032 inch) are required. The tinned trigger lead wire should be trimmed to approximately 3/64 to 1/16 inch length before tack soldering to the P.C. board solder pad location. The solder pad will probably already have a component lead soldered in place. The added connection will be placed on the existing solder and heated momentarily to flow the solder on the wire together with the solder on the component solder pad. Do not allow solder to flow to other solder pads.
The wire you have connected should be secured to prevent strain on the soldered connections using a small tie-wrap or electrical tape. Re-assemble the set taking particular care to be sure the hook switch plunger and spring(s) are installed correctly if they have been removed or disturbed.
The connector on the end of the switch hook lead connects next to the power jack on the rear of the M6500Pv5.
A standard D8W or similar type cord is used to connect to the output jack on the M6500Pv5. 2 pairs are used for output:
| OUTPUT JACK WIRING | ||||

The M6500Pv5 RIM is primarily designed for use with "K" type handsets, having electret microphones. The Merlin MLX series voice terminals use this type of handset. Other voice terminals equipped with "K" type handsets may work with the M6500Pv5 RIM. The M6500Pv5 will not work on sets having carbon type microphones.
