Suunto Mosquito User Manual page 7

Perform pre-checks. Always activate and check the device before diving in
order to ensure that all Liquid Crystal Display (LCD) segments are completely
dis played, that the device has not run out of battery power, and that the oxygen,
altitude and personal adjustments are correct. Also, exit the Data Transfer
mode before diving, as the computer does not automatically revert to Dive
mode from Data Transfer mode.
You are advised not to fl y any time the computer counts down the no-fl ying
time. Always activate the computer to check the remaining no-fl y time
prior to fl ying. The computer goes into the stand-by display automatically 5
minutes after sur fac ing. Flying or traveling to a higher altitude within no-fl y
time can greatly increase the risk of DCI. Review the recommendations given
by Diver's Alert Network (DAN) in chapter 3.2.3.4. "Flying After Diving".
There can never be a fl ying after diving rule that is guaranteed to completely
prevent decompression illness!
The dive computer should never be traded or shared between users while it is in
operation. Its information will not apply to someone who has not been wearing
it throughout a dive or sequence of repetitive dives. Its dive profi les must match
that of the user. If it is left on the surface during any dive, it will give inaccurate
information for subsequent dives. No dive computer can take into account dives
made without the computer. Thus any diving activity up to four days prior to initial
use of the computer may cause misleading information and must be avoided.
