The CU 700 has been designed specifically for use with the DMS 700 wireless system.
The charger provides two charging slots specially shaped to accept the DHT 700 and DPT 700 transmitters. The charging slots operate completely independently so you can charge two transmitters with
rechargeable batteries simultaneously.You do not need to remove the batteries from the transmitter for
charging.
The CU 700 charger
• monitors battery voltages and temperatures during charging;
• generates a flag signaling the end of the charging cycle upon reaching maximum capacity;
• monitors all required safety parameters and will stop the charging cycle if one or more safety parameters are out of range.
The charger checks the batteries inside the transmitter and will automatically deactivate the charging
function if it detects a dry battery.

Operating Notes
5
• Rechargeable batteries (those included or those you may buy later) are delivered uncharged or partially charged. Therefore, you will need to charge each new battery before
using it.
• The battery capacity indication will work best if you charge the batteries fully using the
CU 700 charger.
• If you replace the rechargeable batteries inside a transmitter be sure to fully charge the
batteries in order to calibrate the charging control system.
• Battery life depends on battery quality. Do not use any rechargeable batteries other than
the same type as those included with the charger.
Each charging slot features a tricolor STATUS LED that indicates the current operating status of the respective charging slot (">…<" marks an LED flashing in the respective color):

Important Notes
1. You may safely remove the transmitter at any time before the charging cycle is completed.
2. You may safely charge the batteries inside the transmitter at any time, even before the batteries
are completely discharged.
3. At ambient temperatures above +40°C, the charger may overheat. As a result, the charging cycle
may take considerably longer or stop altogether (STATUS LED flashing red).
As soon as the ambient temperature drops below +40°C, the charging cycle will be resumed automatically (STATUS LED will be lit red).
4. If the batteries heat up to more than +60°C during a charging cycle (e.g., due to high ambient temperature), the charging cycle will be stopped automatically (STATUS LED flashing red). Most batteries will be unusable after being heated up to more than +60°C.
5. Excessive vibrations may cause the charging cycle to be stopped (STATUS LED flashing red),
restarted (STATUS LED is lit orange), or appear completed (STATUS LED lit green) ahead of time.
Make sure the charger will not be subjected to vibrations during the charging cycle and will rest
firmly on a hard surface.
6. Items 1 and 2 above notwithstanding, if you wish to extend the useful life of rechargeable batteries be sure to
• completely discharge the batteries every time, i.e., not to charge the batteries before the bat-
tery warning appears on the transmitter display;
• charge the batteries to capacity every time, i.e., not to remove them from the charger before
the charging cycle is completed;
• avoid charging batteries at temperatures below +5°C or above +40°C. At such temperatures,
the charging cycle will not start and the STATUS LED will be lit orange.
The charging cycle will be resumed automatically as soon as the battery temperature returns
to the acceptable range.
• use no batteries other than the rechargeable types recommended in section 9 Specifications.
7. Rechargeable batteries will only reach their full capacity after several charging cycles.
8. If a transmitter with fully charged batteries and another one with dead batteries are in the charging slots, the charging cycle may take up to ten hours.
9. If you insert a transmitter with a dry battery into the charger, the charging cycle will be stopped
immediately after the battery test and a few minutes of charging. The STATUS LED will start flashing red.
