How to charge the Surface Unit
There is no need to remove the battery pack from the earcup. Plug your
charger CHG-QC1-NIMH into the mains power, then look for the button hole
in the battery ear cup. Plug the DC power plug into the battery pack and
wait until the charge lights indicate full charge (may be seen if the battery
pack is removed).
Make sure that the Surface Unit is OFF while charging.
Also charge the battery in a cool environment. Direct sunlight will overheat
the battery and it will not accept a charge until cool enough.
Do NOT immerse the battery pack. Doing so will void the one year
warranty.

Transducer
Uncoil the transducer cable and put the transducer into the water. Place the
transducer at the same depth as the diver, or as deep as possible but not
right on the ocean floor. Secure the cable to the side of the vessel. Allow
yourself sufficient cable to move about.
1. Apply a small coating of grease, such as Dow Corning® 4 Electrical
Insulating Compound, onto the contacts of the extension cable plug.
2. Plug the transducer into the connector at the bottom of the ear cup.
Caution: The transducer is most subject to damage
when it is attached to the extension cable, as it can
swing easily and hit objects while being lowered into
the water. Particular care must be taken to avoid this
occurrence.
3. Lower the transducer into the water and position it below the
thermocline. If there are excessive currents in the area, or if
operating while under way, attach a small weight to the transducer
to prevent it from drifting upwards or away from the boat.

Power ON and Volume Control
Power up the DIVELINK by rotating the volume control knob clockwise. To
conserve battery power and operating time it would be best to wait until the
diver is in the water before turning ON the DIVELINK. To turn OFF, rotate
the knob anti-clockwise until you hear a "click".
Adjust the volume control to suit your hearing. The DIVELINK has an
automatic squelch circuit to eliminate background noise, so bear in mind that
you may not hear much sound until a diver speaks into another DIVELINK.
Push To Talk Button
Speak into the DIVELINK while pressing the Push To Talk button located at
the TOP of the ear cup. Speak with
your mouth within one centimetre
from the microphone. When you
finish speaking, release the button
and you will hear other DIVELINK
transmissions.
Remember that the microphone is
NOISE CANCELLING. If speak into
the microphone with the front and
back ports at right angles to your
mouth, you may not be heard by the
diver.
Audio Outputs
Two electrical outputs are provided:
1. The LINE OUTPUT allows
surface-to-diver and diver-to-diver
conversations to be fed to external
sound equipment. This output has
been conditioned to provide a standard audio line level signal to the "LINE
IN" jack of youraudio tape recorder, video tape recorder or public address
system. (You will need to purchase a LINE-to-MIC pad to plug this signal
into a camera Microphone Jack.)
2. The SPEAKER OUTPUT will drive an 8 ohm loudspeaker, which plugs
into the DIVELINK "SPKR" jack with a 3.5 mM mono plug.
These audio outputs and the antenna are electrically isolated from the

COM-S01R (All Models) Surface Units
10
DIVELINK electronics to prevent ground loops and to reduce noise when
receiving distant signals.
OPERATING TIPS
PRE-DIVE CHECK The DIVELINK can transmit and receive in air over
a short distance (up to 30 cM). A functional check may be performed before
a dive by speaking into one DIVELINK and listening to a second DIVELINK.
BATTERY To conserve battery power, keep the DIVELINK turned off
until necessary.
CARE AND MAINTENANCE
During use, be very careful not to allow water to splash onto or inside the
DIVELINK headphones, microphone, or any of the plugs connecting to the
DIVELINK. Salt water splashed onto any electrical connection will degrade
performance, since salt water is conductive and will short out or eventually
corrode a connection. If salt water is splashed onto a plug, it should never
be connected to the DIVELINK. It should be wiped off with a damp cloth
dipped in fresh water, and allowed to dry before use. As a general
maintenance procedure, silicone grease may be applied to allplugs to
prevent long term corrosion.
Cleaning
Do not clean the DIVELINK with isopropanol, acetone or other harsh
solvents. A weak detergent solution in a damp cloth is all that is necessary
to remove dirt from the earphones. During cleanup, do not allow water to
run freely around the headphones.
Storage
The SURFACE DIVELINK should be stored in a dry environment to prevent
long term corrosion of the audio and battery terminals.
Handling
Do not drop or jar the DIVELINK. The antenna located at the end of the
cable is sensitive to sudden mechanical shock. Do not stretch or cut any
cables. A cut in the antenna cable will allow salt water into the sealed jacket
and eventually corrode the wires.

WHAT TO EXPECT WHEN COMMUNICATING
UNDERWATER
Barriers to Transmission
Several factors can be barriers to sound transmission in the water.
Water density. Sound transmission can be interrupted by a change in water
density, most typically by the thermocline. (The thermocline is a layer of
water located typically within ten feet of the ocean surface; it has a markedly
different temperature than the water below ten feet.)
Important!: It must be understood that it is not always possible for
the Surface Unit transducer, if it is located over the thermocline, to
communicate with divers under the thermocline. In addition, if the
transducer is lowered below the thermocline, it should not be
allowed to touch the ocean floor.
Wave action or sea floor. Sound transmission can be reduced by wave
action at the surface, or by the sea floor.
Background noise. Sound transmission range can be reduced by
“background” noise, which is generated by a rough sea, by rain, by
biological noise such as a snapping shrimp, or by man-made noises such as
engines and high speed propellers.
Body shadow. Long-range sound transmission can be affected by the
position of the diver’s body in relation to the DIVELINK equipment. A range
reduction can occur if the diver’s body is in the line of sight between his/her
equipment and that of another diver or a Surface Unit.
This effect is known as body shadow. It is caused by the absorption of
sound by air inside the diver’s dry suit, or by air in the diver’s lungs. To
prevent body shadow, the diver should turn 45° so that the line of sight
between the DIVELINK equipment is restored.
Factors not affecting sound transmission. On the positive side,
underwater sound transmission is not affected by muddy or turbid water,
and is equally good in fresh and salt water.

COM-S01R (All Models) Surface Units
12
Range Considerations
In consideration of the barriers to sound transmission underwater (see the
section entitled Barriers to Transmission), use the following guidelines for
optimal range:
Divers should report the position of the thermocline to other divers
and surface personnel.
Avoid trying to transmit through a solid object, such as a ship’s hull
or an underwater cliff. Attempting to do so causes the sound
transmission to be a product of reflections from the surface, the
ocean floor, or underwater objects.
Keep the transducer away from the ocean floor, and as close as
possible to the same depth as the diver.
Chemical Neutralizing Fluid
It is possible that the transmission range can be reduced by a thin layer of
air bubbles blocking the ultrasonic signal at the antenna. In open water, this
will not be the case, but when used in a pool that has been recently
treated with chemicals, a thin layer of bubbles can build up on plastic
surfaces. This is prevented by the use of the CHEMICAL NEUTRALIZING
FLUID, DIVELINK part number CNF-01. The antenna is the black knob at
the end of the cable. A coating of this liquid around the antenna cylinder is
all that is required before every use.
