Battery Notices

This Unitech RH767 is equipped with a Lithium-Ion Battery Pack and a Backup Battery.

However, the RH767 may not start without an external power source due to battery discharge

after extended storage periods. To charge the battery to full capacity, connect the RH767 to

an external power source with the USB Charging Cable or the Unitech RH767 Cradle. Initially

charge the RH767 for at least 16 hours.

The Backup Battery will receive power from an external power source, or through the main

battery (But, only if the main battery has adequate power). In order to prevent data loss due

to Backup Battery failure, connect the RH767 to the main Battery Pack or an external power

source.

NOTE:

Turn the RH767 Backup Battery Switch to the ON position before initial use.

To garauntee optimal performance, replace rechargeable batteries every year or after 500

charge/discharge cycles. It is normal for the battery to physically expand after one year or

500 cycles. Although it does not cause harm, the battery can not be used again and must be

disposed of according to local battery saftey disposal procedures.

If the performance decrease is greater than 20 percent in a Lithium-Ion battery, the battery is

at the end of its life cycle. Do not continue to use the battery, and ensure that the battery is

properly disposed.

The length of time that a battery power lasts depends on the battery type and how the device

is used. Conserve battery life through the following:

Avoid frequent full discharges because this places additional strain on the battery. Several ●

partial discharges with frequent recharges are better than a deep one. Recharging a

partially charged Lithium-Ion battery does not cause harm because there is no memory.

Keep the Lithium-Ion battery cool. Avoid a hot car. For prolonged storage, keep the battery ●

at a 40 percent charge level.

Do not leave the lithium-Ion battery discharged and unused for an extended time period ●

because the battery will wear out and the longevity of the battery will be at least shorter

than half of the one with frequent recharges.

Battery Charge Notice

It is important to consider the environment temperature when charging the Lithium-Ion Battery

Pack. Charging is most efcient at room temperature or in a slightly cooler environment. It

is essential that batteries are charged within the temperature ranges of 32º F - 104ºF (0°C

- 40°C). Charging batteries outside of the specified temperature range could damage the

batteries and shorten their charging life cycle.

CAUTION!

Do not charge batteries at a temperature lower than 32ºF (0°C), which will

increase the internal resistance to cause heat and make the batteries unstable

and unsafe. Please use a battery temperature detecting device for a charger to

ensure a safe charging temperature range.

Storage and Safety Notice

Although charged Lithium-Ion batteries may be left unused for several months, their capacity

may deplete due to buildup of internal resistance. In this case they will require recharging.

Lithium-Ion batteries may store at temperatures between -4Fº - 140Fº (-20°C to 60°C). But

the batteries may deplete more rapidly at the warmer end of this range. It is recommended to

store batteries at room temperature.
