Problem
Solution
The unit will not power up.
Make sure the Lithium Ion battery is properly
installed and the switch is in the proper position
. If the switch is in the AAA position
,
make sure batteries are installed with the proper
polarity. Replace the batteries if low battery voltage.
Phone generates an error message
when plugged into the TK-669D.
A lower voltage output may result in error messages
on the phone but should still charge the phone.
My Ipod / IPhone does not display the
charge signal.
The output voltage of the TK-669D is lower than the
operating voltage of the IPod / IPhone, and will not
charge these devices until the battery is fully
discharged.
The device is only intended for emergency charges
and not for topping off already charged devices.
The TK-669D will no longer hold a
charge.
Replace the 3V lithium ion rechargeable battery
(ICR16340). Typically, this battery will hold 2000
charge cycles.
The TK-669D will not fully charge my
smart phone.
Charging a smart phone through the Phone Charger
Jack is intended for emergency purpose only. It is not
intended for recharging fully a discharged battery.
Smart phone battery capacity significantly exceeds
the battery capacity of the TK-669D.
Therefore, a fully charged TK-669D will only partially
charge a smart phone or mp3/mp4 device. After the
battery stops charging the device, disconnect the
device and begin cranking if a DC power source is not
available.
