    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.

    (Fig. 1, #7 and Fig. 3, #22). • Do not charge alkaline or heavy-duty batteries. Damage to the STX-101/M/ SB, an explosion, and/or injury may occur.
  • Page 13: Section 3: Operation

    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.
  • Page 14 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.
  • Page 15: Section 4: Maintenance

    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.
  • Page 16: Section 5: Helpful Hints And Tips

    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.
  • Page 17: In The Beginning

    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.
