How to install 2nd stage regulator into the Spectrum FFM?
Remove the bite mouth piece (if installed) from the second stage regulator. Insert second stage regulator mouthpiece tube into the regulator port through the front of the Spectrum FFM. Install military standard (MS3367-7-0) zip tie tightly around second stage regulator so that it wraps around and fastens the mouthpiece tube securely to the Spectrum FFM.
What are acceptable 2nd stage regulators?
The regulator port of the Spectrum FFM allows regulators from 3/16" x 5/8" and sizes up to 1-7/16" x 13/16". Most standard 2nd stages should be compatible.

The OTS Buddy Phone® D2 is a digital, micro-miniature, ultrasonic transceiver allowing communication between two or more scuba divers or surface stations. Using "Digital Signal Processing" (DSP) techniques, the OTS Buddy Phone produces uncompromising speech clarity.The OTS Buddy Phone® D2 differs from the standard Buddy Phone in that it is digitally controlled and has some fantastic new features such as: a voice menu to guide you adjust your Volume, change from Channel A to Channel B, or put the Buddy Phone in a continuous voice transmission mode.
Voice Menu: When you submerge with a D2 Buddy Phone, you will hear the voice system say "Buddy Phone ON, frequency A (B), channel one (four), volume High (Medium, Low)," depending on the prior dive's settings. Changing a setting is easy and can be done while underwater. Depress the Push-to-talk switch (PTT) three times quickly and hold the third depression until you hear "main menu - volume, channel, continuous transmit." When you hear the main menu selections, simply depress the PTT to select one of the choices. The unit will make the selection and go back to the receive mode. If you don't make a selection after the menu repeats twice, the D2 Buddy Phone goes out of the main selection menu and back to the receive mode (see operators manual for a more detailed explanation -- note: continuous transmit mode allows the user to talk, hands free. This was requested by many movie makers and scientists who talk on camera often).
