Battery Maintenance
2. Lithium batteries are of no memory effects, thus support charging on demand. lt
will extend battery lifespan with incomplete charge cycle.
3. When quantity is running low level, it is highly suggested the battery is charged
immediately to avoid irreversible damage. Do NOT charge the battery continu­
ously over 24 hours. Charge the battery for 0.5 – 1 hour with matching charger
every 3 months when it's idle, to ensure the battery keeps 40 % – 60 % quantity.
4. Long­term storage (over 3 months) requires an environment with temperature of
20 ±10°C (10 – 30°C) and humidity of 65 ±20%RH. Lithium battery service life is
affected by temperature. 0 – 40°C is the ideal environment.
5. Knocking, needling, watering and treading are harmful to battery.
Keep the battery away from heart pacemaker, flammable gas, sun exposure,
microwave and high pressure. Do NOT dismantle the battery to avoid safety risks.
6. During the charging or discharging process of the lithium battery, if there are
odors and noises or it expands or runs out, stop charging or discharging imme­
diately and contact your Rollei retailer.
Description of continuous flash shooting:
If the flash fires continuously at full power for a longer period of time, the tempe­
rature of the flash head will increase. To prevent the flash head from being worn or
damaged by overheating, the HS Freeze 2s automatically activates the overheating
protection and initially reduces the recycling time. At a temperature of 25°C, the
flash fires continuously at full power every 1.3s for approximately 50s, then the
recycling time is automatically extended to 2s and the flash continues firing until
the overheat protection is activated and "OH" appears on the display. The symbol
disappears again when the flash cools down.
