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.

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.

can transfer the call to the headset by pressing the answer/end key on the headset  
briefly.  
To answer a call with the headset, press the answer/end key on the headset briefly.  
There may be a slight delay in transfering the call from the mobile phone to the  
headset. To avoid missing calls, it is recommended that you answer calls with your  
mobile phone, and then transfer the call to the headset.  
If you do not want to answer a call, press and hold the answer/end key on the  
headset for a second.  
To make a call, dial the number with your mobile phone and press the answer key  
on your phone. Then press the answer/end key on the headset to transfer the call  
to the headset.

answer/end key on the headset, and proceed with the voice dialing as described in

To end a call, press the end key on your mobile phone or the answer/end key on  
your headset.  
Standby mode  
To maximise the battery life, the headset automatically switches off after each  
call. To prevent this, set the headset in the standby mode. The standby mode  
speeds up the connection to your mobile phone, but reduces battery life. To  
activate the standby mode, press and hold the volume and answer/end keys for 5  
seconds.  
To switch the headset on in the standby mode, press the answer/end key. To  
switch the headset off in the standby mode, press and hold the answer/end key for  
5 seconds.  
Light indicator  
The HS-37W headset has a yellow light indicator (LED). When you insert or replace  
the battery and switch the headset on, the LED lights up. This indicates that the  
headset is in the pairing mode. When the power level of the battery in the headset  
is getting low, the LED flashes twice every 5 seconds. Replace the battery.  
Use the headset on the left ear  
The HS-37W headset is ready to be worn on the right ear. If you want to use it on  
the left ear, gently rotate the earpiece.

Store the headset  
Always store the headset with the power off and safely protected.  
Avoid storage in high temperatures (above 45°C / 113°F) - such as direct sunlight.  
Storage in high temperatures can degrade performance and reduce the battery  
life. Low temperatures (down to -10°C / 14°F) shorten the battery life and may  
affect operation.  
Do not expose the headset to rain or other liquids.  
Troubleshooting  
The audio quality is poor  
Check that the headset is within a maximum of 10 meters from your phone, and  
that there are no obstructions, such as walls, or other electronic devices between  
the headset and the phone.  
There is no audio in the headset  
• Increase the volume on the headset by pressing the volume key.  
• Ensure that the headset is paired with the phone.  
• Make sure that the phone is connected to the headset. If not, try pairing the  
devices again.

the headset, see Standby mode, 11.

otherwise

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.
