In order to prevent any malfunction within your Li-Ion battery pack and to preserve
the capacity as much as possible, there are a number of procedures which must be
considered when storing your battery pack for long periods while not in use (ie.
over the summer months).
Storage and transportation:
Never carry the lighting system by the cable. This could result in damage to the
electrical connections and will invalidate your warranty.
Always disconnect the lamp unit from the battery pack when not in use. When the
lamp unit and battery pack are connected there is a small amount of power
constantly running through the circuit which could – over a period of time – over
discharge the battery pack resulting in loss of battery function and capacity. This
will also prevent the lamp unit accidentally switching on and potentially overheat-
ing, which could cause permanent damage to the lamp and battery. In extreme
cases, overheating could cause fire and/or death.
Storage Temperature:
The battery pack should be stored within the temperature range of -20°C to 25°C in
order to preserve cell capacity. Ideally in a cool, dry room such as a cellar or garage.
Over discharging:
As with most battery cells, Li-Ion cells may discharge if they are not used for a long
time. In order to prevent over discharging fully charge the battery pack before you
store it. Also, charge the battery pack periodically (ie. once every 3-4 weeks) to
maintain the voltage between 6.8V to 7.6V. Over discharging may cause loss of cell
performance, or damage battery function.
If these few procedures are followed correctly, you can be sure that when the dark
nights creep back in your HOPE VISION battery pack will be fit and raring to go!
If you find that the power connectors are becoming difficult to separate, we advise
using a small amount of silicone lubricant on the battery connector to ease fitting.
There are no serviceable parts inside either the light unit or battery pack. Please do
not attempt to disassemble the units, as this will invalidate the warranty. If you find
that there is a problem with the functioning of the lighting system please first
check that the battery pack is fully charged (see Charging the Battery Pack section).
If the light still fails to function please contact Hope Technology.

Note:
The R4 lamp includes an ‘energy preserve’ feature whereby the power will automati-
cally drop down from mode 3 to mode 2 towards the end of the battery discharge
cycle (i.e. after approximately 2 hours 30 minutes in mode 3 with the 5200mAh
battery, depending on conditions). This is to prolong the remaining 20-25% of energy
within the battery. If you attempt to select mode 3 during the energy preserve period
the lamp will immediately fade back down to mode 2 and block the selection of
mode 3 in order to maximise the remaining battery life. Operation of the lamp then
continues with only modes 1 and 2 remaining active with each subsequent press of
the power button. Mode 3 is no longer selectable. This is a deliberate characteristic of
the drive circuit and should not be interpreted as a malfunction.
The R4 also features a low battery warning mode. When the battery is almost at the
end of it’s discharge cycle the lamp will drop down into low power mode and flash
twice every 15 seconds to warn you that you are running low on battery life. Once the
lamp unit has dropped into low battery mode, no other modes are selectable.
Pressing the power button will only turn the lamp off or on.
The battery charger is designed for indoor use only and should not come into
contact with water.
The mains socket should be easily accessible. In the event of any operational
error the plug should be immediately removed from the mains supply.
The battery charger contains dangerous voltages and the cover should not
be removed. Any attempt to open the charger will invalidate the warranty.
NOTE: The rechargeable battery pack is supplied with a small charge for testing
purposes only. Therefore, it is recommended that the battery pack be fully
charged before first use.
To correctly charge the battery pack, ensure these steps are followed in order:
· Disconnect from the light unit by pulling apart the two mating dc connectors.
Never disconnect the battery from the light unit by pulling the cables. Always use
the connector strain relief for grip when disconnecting.
· Before connecting the charger to the mains supply, plug the charger into the
battery pack (1).
· Once the battery pack is connected to the charger it can then be plugged into
the mains power supply (2). The charger’s LED indicator will show as red when a
discharged battery is connected. We recommend that the two mating connectors
are rotated at this point (3) to ensure that a good connection is made between the
battery pack and charger, and that the LED indicator turns red.
· When charging is complete, the charger’s LED indicator will turn green.
Disconnect from the mains power supply before disconnecting the battery pack
from the charger.
Charge Times: A fully discharged 5200mAh battery should take approx 6 hours to
fully recharge. The 2600mAh battery pack takes approx 3 hours to fully recharge.
DANGER: Use only the 7.4v Li-Ion battery pack supplied with the lighting
system. Any attempt to use or charge another battery pack may result in
explosion and serious injury.
