• Complies with FCC Part 15, Class B. Changes or modifications not expressly approved by the responsible party could void the user's authority to operate the equipment.

System Overview

The RETRO-M system is made up of 5 possible components:

• Master Unit — controls music and intercom functions: volume, bass/treble, clock, privacy settings, and includes an integrated docking station for portable music players (charges via USB or Firewire, plus a 3.5mm audio input jack).
• Room Station (RETRO-5R) — indoor use; selects between intercom, radio, and portable music sources; can turn the radio on/off; communicates with other stations including master and door stations.
• Patio Station (RETRO-5P) — weather-resistant, for protected outdoor areas; provides intercom and music, with door chime playback. No LISTEN button (security).
• Door Station (RETRO-D) — outdoor use in protected areas; allows communication with master, room, and patio stations to verify visitors before opening the door.
• Auxiliary Input Wall Plate — optional, maximum one per system.

Note: Due to the variety of portable music devices and charging modes, not all devices are guaranteed to charge via the docking station's Firewire/USB ports.

Operational Controls

• MENU/ENTER buttons — multi-functional switches used with the LCD display for programming.
• Volume — controls the volume of the unit it's located on (master, room, or patio individually).
• Audio On/Off — shuts off AM/FM radio and MP3 music at master and all room stations (does not affect intercom). Hold 3+ seconds to monitor the door station.
• UP/DOWN and LEFT/RIGHT buttons — scroll menus, change radio presets/frequency, change characters, move display cursor.
• Privacy — prevents a station from being monitored by others.
• Listen — hands-free reply mode; built-in mic picks up voice in most room sizes.
• Talk — broadcasts an "all call"; once a station responds within 25 seconds, the call becomes private between the two stations (Automatic Selective Call) and all other stations return to their prior audio.
• Unlock the Door — unlocks a door from master or room stations (optional feature, only if installed).
• Set — hold 5 seconds to turn radio on/off; press momentarily to scan radio presets.

Monitor

Turn Monitor On/Off; use Select to choose which stations to monitor (Y/N per station); set Type to Normal (listen only, no talk) or Override (monitored room can answer intercom calls). Press EXIT to leave the setup screens.

Radio Presets

10 presets, each assignable to AM or FM. From the radio screen, press ENTER, choose AM or FM, tune to the desired frequency, press ENTER (SAVE), then pick the preset number (1–10) with UP/DOWN and press ENTER. Hint: hold LEFT/RIGHT for 3 seconds to engage automatic seek.

Selecting the Input Source

Press ENTER from the main screen to reach Source-Select. Use LEFT/RIGHT to choose FM, AM, or AUX, then ENTER to activate. An asterisk (*) marks the current source. There are two aux inputs — the docking-station 3.5mm jack takes priority over the optional wall-plate aux input if both are connected simultaneously.

Room & Patio Station Operation

Room stations have Source, Listen, Talk, Volume, Set, and Privacy buttons. SOURCE cycles between AM/FM radio and Aux 1/Aux 2 (mirroring whichever input is active at the master). LISTEN and TALK handle intercom; TALK is an all-call until a station answers, then the call goes private (Automatic Selective Call) and other stations resume their prior audio. PRIVACY blocks other stations from monitoring this one. SET toggles the radio (5-second hold) or scans presets (momentary press) — and post-2013 units also use SET to trigger the optional door-unlock feature. Hold SOURCE for 5 seconds to listen to the door station; it auto-cancels after 30 seconds of inactivity.

The Patio Station operates identically to the Room Station but omits the LISTEN button for security reasons.

Answering the Door

When the doorbell is pressed, music mutes at the master and room stations and the chime sounds. Press TALK on the master or any room station to answer; release TALK to listen. Communication with the door station stays active as long as there's ongoing dialogue, and deactivates automatically after 30 seconds of silence.

Door station speaker volume is adjusted via a screw on the back of the door unit's circuit board (accessible only by opening the unit).

There are 5 selectable door chimes: MENU → UNIT → select door station → ENTER → CHIME → ENTER, choose 1–5, ENTER to save, MENU ×3 to return.
