In case the transmitter battery is running low, a low battery warning 
“LOBT” will be transmitted and displayed intermittently with the pressure 
reading on the Vytec (Fig.2.6 d).

If the dive is started without that the Vytec and the transmitter have been 
properly paired, the Vytec will indicate that no cylinder data is available 
by displaying “OFF”  (Fig. 2.6 e).
