2.4.2. Pairing and Code Selection
In order to receive wireless data the transmitter and the Vytec wrist unit
need to be paired. During the pairing procedure the transmitter and wrist
unit select a common transmission code.
The transmitter turns on when the pressure exceeds 15bar [218 psi] and
it then starts sending pressure data together with a code number. During
the pairing procedure the Vytec stores the above mentioned code number
and starts displaying pressure values that are received with that code.
This coding procedure inhibits data mix up from other divers also using
the Vytec’s transmitter.
When there is no stored code the Vytec will display “SETC” and receive
with lowered sensitivity from a very short distance only (Fig. 2.6 a). By
taking the Vytec close to the transmitter it will store the received code
and start receiving with full sensitivity and display data received with this
code only. The code is held stored for approximately 2 hours, or until the
cylinder pressure goes below 10 bar [145 psi]. The set code can also be
manually erased by the user.
To pair the transmitter and the wrist unit:
1. Make sure that the transmitter is properly attached to the regulators
HP port and that the regulator is properly attached to the cylinder.
2. Ensure that the Vytec is turned on, an that the wireless integration is
enabled in the Vytec’s settings (HP set on, see chapter 4.3.3.3). The
Vytec should display “SETC” in the lower left corner.
3. Slowly open the cylinder valve fully and pressurize the regulator. The
transmitter will start transmitting when the pressure exceeds 15bar
[218 psi].
4. Take the Vytec wrist unit close to the transmitter. The Vytec will now
shortly display the selected code number and then start displaying
the transmitted cylinder pressure. A lightning symbol will be displayed
every time the Vytec receives a valid signal.
WARNING:
In case there are several divers using Vytecs with wireless trans-
mission always ensure that all divers are on different codes before
starting the dive.
