2.4 Heat Reflective Shields
Newer model vehicles may have a heat reflective shield embedded in the windshield
preventing proper GPS signal reception if the receiver is placed behind the windshield.
To enable proper reception:
(a) Use an external antenna, or
(b) Place the receiver in a different position, or
(c) Place the receiver behind the rearview mirror, where many vehicles have an opening
in the heat reflective shield, indicated by a black outline
2.5 Magnets
The TomTom Wireless GPS receiver contains strong magnets. Do not place the receiver
near any item that may be damaged by magnetic force, such as credit and debit cards.
2.6 Battery
This product uses a Lithium-Ion battery. Please charge the battery fully before first use.
Refer to operational temperature ranges in the specification appendix. Operation in low
(below 0ºC/32ºF) or high (over 45ºC/110ºF) temperatures will affect power supply
efficiency and the ability to charge the battery. All Lithium-Ion batteries will experience
power supply efficiency deterioration over time, even if not used, and have a limited life
expectancy. Permanently powering the battery will reduce life expectancy. Do not
continue recharging the battery if it does not recharge within the specified time. Do not
pierce, open or disassemble the battery. Do not swallow the battery. If the battery leaks
and you come into contact with the leaked fluids, rinse thoroughly with water and seek
medical attention immediately.
Do not use your product in a humid, wet and/or corrosive environment. Do not put, store
or leave your product in or near a heat source; in a high temperature location; in strong
direct sunlight; in a microwave oven; in a pressurized container, and do not expose it to
temperatures over 60ºC (140ºF). Failure to follow these guidelines may cause the
Lithium-Ion battery to leak acid; become hot; explode; or ignite and cause injury and/or
damage.
THE LITHIUM-ION BATTERY CONTAINED IN THE PRODUCT MUST
BE RECYCLED OR DISPOSED OF PROPERLY. USE ONLY WITH
SUPPLIED CHARGER(s) AND SUPPLIED AC ADAPTOR FOR
BATTERY CHARGING.
