International, Inc., dba Ocean Technology Systems hereinafter referred to as OTS, reserves the right to change specifications without notice. We recommend that all users read and fully understand this manual before using the STX-101/M/SB or any other underwater product. All statements, technical information, and recommendations herein are based on tests we believe to be reliable, but the accuracy or completeness thereof is not guar- anteed;...
32.768 kHz transducer assembly and a hand-held microphone. Optional rechargeable batteries and a charger are available, although alkaline batteries can be used. The STX-101 is designed to operate primarily with the SSB-2010 commercial transceiver but also works great with our standard Buddy...
(alkaline batteries should not be used with the STX-101SB). The system includes a high-quality hand-held microphone. Note: This manual will refer to the STX-101, STX-101M, and STX-101SB transceiv- ers collectively as STX-101/M/SB. Wherever we present information that is not common to all, we will refer to them by their individual model numbers.
RB-6V gel-cell batteries . STX-101SB: Use RB-6V rechargeable batteries only (not alkaline). Battery life (with 10% duty cycle) : STX-101: Alkaline 20 hrs., gel cells 12 hrs. STX-101M: Alkaline 12 hrs., gel cells 8 hrs. STX-101SB: Gel cells 6 hrs. (do not use alkaline) External power: 12 volts DC at a minimum of 4 amps.
(#8). If you are not using the system, disconnect the transducer cable to conserve energy. CHANNEL: The STX-101M has eight channels, the STX-101 has four chan- nels, and the STX-101SB has one channel (Section 1.2, Specifications). If using the STX-101 and you choose an unprogrammed channel, a beeping sound will alert you to select a working channel.
101SB, use only lead-acid rechargeable batteries, not alkaline. BATTERY SElECTION With the STX-101/M, for best results use two 6-volt, heavy-duty, alkaline spring- type lantern batteries: Eveready Heavy Duty Alkaline #528 or Duracell Heavy Duty Alkaline #ID9150 will provide the best results for most diving operations. You can use standard 6-volt, spring-type lantern batteries in a pinch;...
Installing the batteries in the wrong direction (spring contacts away from the printed circuit board) may cause damage to the unit or batteries, and/or the STX-101/M/SB will not operate. lOW-BATTERY AlERT 19.
The charging time for a depleted battery is 4-6 hours. Anytime you are charging the batteries, the front-panel “Battery Charging Relief Valve” (Fig. 1, #7) should be opened. Leave it open and do not operate the STX-101/M/SB for approximately 15 minutes after charging. This procedure will give the system time to dissipate any off-gassing from the batteries.
Ensure all batteries are properly installed and fresh and the front panel is installed without any pinched wires. Place the STX-101/M/SB on a surface that is secure from boat action and in a place where the transducer cable will not trip anyone.

Channel 1 for the STX-101 and Channel 7 for the STX-101M are most efficient and recommended. Connect the hand-held microphone to the microphone receptacle (Fig. 1, #5). If a headset is desired, connect the headset connector to the headset receptacles (Fig.
Inspect the batteries periodically to ensure they are in good order and free of leaks. When the STX-101/M/SB is not being used, it is a good idea to keep the cover securely fastened. Remember, when the transducer assembly is connected to the STX-101/M/SB, the power is on.
PlACEMENT OF THE STX-101/M/SB The STX-101/M/SB should be placed where it can be heard easily. If working out of a boat, locate a place where you can secure the unit where boat action will not cause it to fall. Also, remember to dress the transducer cable in such a way that divers and topside personnel will not trip over it.
be discouraged when first using wireless communications. IN THE BEGINNING If this is the first time you or anyone on your team is using communications, we recommend the team get together to talk about the system. Practice alternative communications in the event something is not working. Plan to use a second chan- nel everyone knows to use in the event someone gets off the working channel.
