ViewZ 5.6" HD-SDI CCTV TEST MONITOR
After the charger is inserted, the LED indicator (green-green-off) acts once; then, it enters the test state,
and the LED indicator flashes fast (red-green-red-green…) for about 13 times; if the battery has no defects,
it will enter the normal charging state.
► State of the LED indicator when the battery level is lower than 50%: red-green-off- red-green-off…
► State of the LED indicator when the battery level is higher than 50%: red-green-red-green-red-green…
► State of the LED indicator when the battery level is 100% (fully charged): constantly green.
► If the charger is inserted again after the battery is fully charged, it will continue to charge for about 30min before stop.
★Note: When the battery is fully charged, please do not repeatedly charge it for several successive times if it is in use; or else,
the battery may be damaged. Please charge the battery when its level is below 10% or when the device can not be turned on
completely; due to the memorability of Ni-MH battery, repeated abnormal charging may shorten the service life of the battery.
► The product is designed with complete circuit protection; when the DC12V output interface has no load access, the DC12V
output voltage is approximate to the current battery voltage and the output current is about 0.5mA. When normal load is accessed,
the circuit will automatically open DC12V output; after load disconnection, DC12V output will not be closed; it is needed to restart
the device to restore output protection.
► When the battery voltage is ≥4.3V, the maximum load of DC12V output is 350mA.
► Over-current and short circuit both can enable the circuit protection, thus to automatically cut off DC12V output. During
protection, the circuit will automatically repeatedly test whether the load is normal at a time interval of 2-3s; when the load returns
to normal, DC12V output will also automatically return to normal.
► This product is designed with the overheating protection function during charging and discharging of the battery; it is set that
the circuit protection will be enabled when the internal temperature of the product is over 62℃, at which moment it is not allowed
to charge the battery or turn on/off the device. The protection cannot be removed by replacing the battery with a new one; it can
be removed only when the temperature of the temperature sensing component on the circuit board returns to normal.
► This product is designed with the battery over-discharge protection function; it is set that the circuit protection will be
enabled when the working current of the product exceeds 2600mA, at which moment the device cannot be turned on to work
properly; the protection can be removed only by restarting the device.
► This product is designed with the battery over-voltage protection function; it is set that the circuit protection will be enabled
when the battery voltage of the product exceeds DC6.5V, at which moment the device cannot be powered on automatically even
when the battery voltage returns to 4.8V; the protection can be removed by turning it off again.
