The selected transmission code can later be
verifi ed via the alternative display, by pressing
the “TIME” button twice. If needed, the stored
code can be manually erased in this display
by pressing the “PLAN” (up) button and then
pressing “MODE” (select). The Vytec will now
erase the stored code and start displaying
“SETC” allowing a new pairing with the trans-
mitter.
The alternative display showing the select-
ed code reverts to the main display after 15
seconds in order to avoid accidental code
changes.
The user can manually change the transmit-
ters code by reducing the pressure to less than
10 bar [145 psi] and then immediately (within
10-12s) increasing the pressure above 15 bar
[220 psi]. The transmitter will now select a new
code. The wrist unit must be in SETC mode to
pair on the new code. This procedure can be
used e.g. if your dive buddy has the same code
and you need to change the code.
NOTE: In order to save battery energy the
transmitter shuts off if the pressure remains
unchanged for more than 5 minutes and it
will continue transmitting with the saved code
when any pressure change is measured.
2.4.3. Transmission Data
After the pairing procedure the Vytec will receive cylinder pressure data
from the transmitter. The pressure is displayed in either bars or psi de-
pending on the unit selection. Any time the Vytec receives an appropri-
ate signal it fl ashes the lightning fi gure in the display’s lower left corner.
A pressure reading of over 360 bar [5220 psi] will display as “---“ (Fig.
2.6 b).
If the Vytec is unable to receive a valid signal for more than one minute
it will start displaying “FAIL” intermittently with the latest valid pressure
reading (Fig. 2.6 c).
