General guidelines
Battery
The TN-206 contains a lithium-ion battery inside.
Leaving the TN-206 in hot or cold conditions, such
as in a closed car in summer or winter conditions,
will reduce the capacity and lifetime of the battery. It
is ideal to keep the TN-206 in a place with a
temperature between +15°C (+59°F) and +25°C
(+77°F). A TN-206 with a hot or cold battery may
temporarily not work, even when the battery is fully
charged. The performance of the lithium-ion battery
is particularly limited in temperatures below 0°C
(+32°C). Temperature extremities will affect the
ability of your battery to charge: allow the TN-206 to
adjust to operating temperature before using.
Recharge the TN-206 with the charger supplied
only. Do not leave the TN-206 connected to the
charger for more than 24 hours. Excessive charging
may shorten battery life. If left unused, a fully
charged battery will discharge itself over time.
GPS Satellite Signal
A longer than normal time-to-first-fix of position may
occur during your first use of the TN-206. Operating
the TN-206 (unit’s logo plate) requires a clear and
unobstructed view of sky with antenna facade
pointing upward to the sky. Tall buildings and other
obstructions to the sky may block satellite signals
and delays.
