Operating instructions

Be sure to charge the battery fully before using it for the
first time or when it has not been used in the last 6 months.
Connect one end of the supplied USB cable to PX1, and the
other end to the Power Adapter. The Power Adapter is rated
110-240 VAC from a wall outlet. You can also charge via the USB
port on your computer.
Battery recharge time is approximately 3 hours, depending on
the remaining charge. Charging through a computer’s USB port
will take longer than using the supplied Power Adapter.
When fully charged, the battery will last for about 50 heat cycles
(60 seconds each) on the highest temperature setting, and 100 or
more cycles on the lowest temperature setting. Maximum tem-
peratures are best generated when the battery is fully charged.
The battery can be recharged approximately 500 times, but
performance may decrease after repeated recharges. Under
normal operations, the battery can be recharged up to 70% of
its rated capacity at the end of the warranty period.
!
! WARNING
Use only the supplied Power Adapter. Do not use other power
adapters which may damage the battery.

mended that you leave the power off until
