Omitted decompression
The Error mode results from omitted decompression, i.e. when you stay above the ceiling
for more than three minutes. During this three-minute period the Er warning is shown and
the audible alarm beeps. After this, the dive computer will enter a permanent Error mode.
The instrument will continue to function normally if you descend below the ceiling within
this three-minute period.
Once in the permanent Error mode, only the Er warning is shown in the center window.
The dive computer will not show times for ascent or stops. However, all the other displays
will function as before to provide information for ascent.You should immediately follow
through the decompression schedule in your backup plan.
After surfacing, you should not dive for a minimum of 48 hours. During the permanent
Error mode, the Er text will be displayed in the center window and the planning mode will
be disabled.
5.8. Wireless transmission
The HelO
2
can be used together with a wireless cylinder pressure transmitter that easily
attaches to the high-pressure port of the regulator. By using the transmitter, you can be-
nefit from receiving cylinder pressure data direct to your wrist.
In order to use thetransmitter, the wireless integration needs tobe enabled in your Suunto
HelO
2
settings. To enable or disable the wireless integration refer to Section 5.9.7. Setting
the tank pressure.
5.8.1. Installing the wireless transmitter
When purchasing the Suunto HelO
2
, we strongly recommend that you have your Suunto
representative attach the transmitter to the first stage of your regulator.
However, if you decide to attach it yourself, do the following:
1.
Remove the high pressure (HP) port plug on the first stage of your regulator using an
appropriate tool.
2.
Thread the high pressure transmitter of the Suunto into the HP port of your regulator
with your fingers. DO NOT OVERTIGHTEN! Maximum torque is 6 Nm/4.4 lbsft or 53
lbsin. The seal is based on a static O-ring, not force!
3.
Attach the regulator to the scuba cylinder and slowly open the valve. Check for leaks
by submerging the regulator first stage in water. If leaks are detected, check the
condition of the O-ring and sealing surfaces.
5.8.2. Pairing and code selection
In order to receive wireless data, the transmitter and the Suunto HelO
2
need to be paired.
During the pairing procedure, the transmitter and dive computer select a common trans-
mission code.
The transmitter is activated when the pressure exceeds 15bar/218 psi and it then starts
sending pressure data together with a code number. During the pairing procedure, the
Suunto HelO
2
stores the code number and starts displaying pressure values that are re-
ceived with that code. This coding procedure inhibits data mix-up from other divers also
using a Suunto HelO
2
transmitter.
When there is no stored code, the Suunto HelO
2
displays “cd:--” and receives data with
lowered sensitivity from a very short distance only. By taking the Suunto HelO
2
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 stored until you reset it manually.
To pair the transmitter and the Suunto HelO
2
dive computer:
1.
Make sure that the transmitteris properly attached to the regulator’s HP port and that
the regulator is properly attached to the cylinder.
