1. Introduction
Read this user guide carefully before using the headset. Read also the user guide
for your phone, which provides important safety and maintenance information.
Keep the headset out of reach of small children.
The Nokia Bluetooth headset HS-37W is designed for all-day wear, and provides
up to 15 hours of talk time with a single AAA battery.
This device is intended for use when supplied with power from a 1.5 V LR03 / AAA
Alkaline battery. The use of any other types may invalidate any approval or
warranty, and may be dangerous. Always switch the device off before removing
the battery. Ensure the correct polarity is observed when inserting the battery.
Do not try to recharge the battery unless the manufacturer of the battery has
intended the battery to be rechargeable.
■Bluetooth wireless technology
The HS-37W headset can be connected to a compatible mobile phone that
supports Bluetooth wireless technology. The Bluetooth wireless technology makes
it possible to connect compatible communication devices without cables. A
Bluetooth connection does not require that the phone and the headset be in line
of sight, but both devices should be within 10 meters of each other. Connections
can be subject to interference from obstructions, such as walls, or other electronic
devices.

6Copyright © 2005 Nokia. All rights reserved.
The HS-37W headset is compliant with the Bluetooth Specification 1.2 supporting
the following profiles: Headset Profile and Handsfree Profile. Interoperability
between the HS-37W headset and other Bluetooth-enabled products is not
guaranteed. Check with the manufacturers of other devices to determine their
compatibility with this device.

Care and maintenance
Your device is a product of superior design and craftsmanship and should be treated with
care. The suggestions below will help you protect your warranty coverage.
• Keep all accessories and enhancements out of the reach of small children.
• Keep the device dry. Precipitation, humidity and all types of liquids or moisture can
contain minerals that will corrode electronic circuits. If your device does get wet, remove
the battery and allow the device to dry completely before replacing it.
• Do not use or store the device in dusty, dirty areas. Its moving parts and electronic
components can be damaged.
• Do not store the device in hot areas. High temperatures can shorten the life of electronic
devices, damage batteries, and warp or melt certain plastics.
• Do not store the device in cold areas. When the device returns to its normal temperature,
moisture can form inside the device and damage electronic circuit boards.
• Do not attempt to open the device other than as instructed in this guide.
• Do not drop, knock, or shake the device. Rough handling can break internal circuit boards
and fine mechanics.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the device.
• Do not paint the device. Paint can clog the moving parts and prevent proper operation.
All of the above suggestions apply equally to your device, battery, charger, or any
enhancement. If any device is not working properly, take it to the nearest authorized service
facility for service.
