7. Care and maintenance – a little
goes a long way
The Kalhuohfummi is robust, tough and easy to clean. However, like every device with a rechargeable Li-Ion battery, there are
several things you can do to ensure efficiency and reliability. Before you contact our customer service team, please ensure you
read the notes in Chapter 8 about the care and operation of your device.
• Remember, the Kalhuohfummi is a battery. Prolonged exposure to direct sunlight
may cause overheating.
• Protect the device against vibrations and shock.
• Keep it free from dust and moisture and ensure it does not overheat.
• Place no flammable, explosive or dangerous objects in the vicinity of the device.
• Never attempt to open the device or repair it yourself.
• Protect the device from rain, humidity and do not place it in liquids.
• Use the device only at a temperature of – 20 °C (– 4 °F) to + 60 °C (140 °F).
• If the Charger is not in use, disconnect all cables.
Your Kalhuohfummi stores its energy in rechargeable Lithium-Ion batteries. Their capacity
is measured in Wh (Watt-hours.) Over time these batteries naturally lose their maximum
recharging capacity. Following the guidelines below will ensure a long life of happy, efficient
charging for your batteries.
• The battery should never be exposed to temperatures above +60 °C (140 °F).
The optimal ambient temperature is between 0 °C to + 40 °C (32 °F to 104 °F).
• Any prolonged storage of the battery should be done with a battery charge of about 50%
(equivalent to two or three LEDs on the display). Failure to do so can result in deep battery
self-discharge, which can damage the battery cells.
• Note the disposal instructions of batteries! (see Chapter 9, Disposal)
