Charging the headset

  1. Open the cover of the micro-USB port.
Insert the tip of your fingernail in the groove, and open the cover.
  1. Connect the supplied micro-USB cable to the headset, and then connect the other end to a computer.
Make sure that you connect the plug of the micro-USB cable in the direction as shown in the illustration below.
Charging starts when the headset and the computer are connected.
Make sure that the indicator (red) lights up. Charging is completed in about 6 hours* and the indicator (red) goes off automatically.
*Time required to charge the empty battery to its full capacity
  • If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset and wait until the indicator (red) lights up.
  • When you close the cover of the micro-USB port after charging the battery, push the catch at the edge (the round part) of the cover into the port compartment.

How to Change COS (Class of Service) Password

If you set the all line and set restrictions to no restrictions, you are not restricted from making any calls. I don't think it's the phone system requiring this 4 digit code. Are you sure all your lines are set with the same long distance provider. Did the lines in the dial 8 group require a code. (ie some users had the long distance provider set up their lines to need a code entered to charge calls off to different job codes, so they can distribute the charges correctly).
You should now be able to call 9+1+area code+number, with no restrictions.

CS60 ear peice with heavy static when in use

This may be caused by a few things.

1. Check the configuration dial on the left hand side of the base to see if another setting works better. The recommended setting for most phones is 1.

2. Make sure your speaking (transmit) level is not too high. First, try lowering the volume on the telephone. If you still hear distortion, adjust the volume of the headset. The master transmit controls are the ABCD switch settings on the bottom of the base. A is the lowest and D is the highest setting. You can fine tune this setting with the Plus (+) and minus (-) buttons on the back of the base that are above and below the picture of the microphone.

3. Double check the battery has a full charge.

The Amber Charge light on the base will flash while charging and will stay solid amber when fully charged.

3 hours = full charge

4. Make sure the headset has been paired to the base.

Purple light

The purple (majenta) light usually means it is in pairing mode. Is it possible that the button is stuck pressed in??


1. Ensure the headset is turned off (indicator light not blinking and headset boom is closed)
2. Press and hold the Call button. After about 4 or 5 seconds, the indicator light becomes steadily lit in magenta
3. Release the Call button and immediately open the headset boom. The indicator light remains lit in magenta.

If the indicator light is flashing in blue or not steadily lit when opening the
headset boom, repeat steps 1 through 3

H700 charges fine, dies in an instant

Open it and see if it has a battery. Take the battery to RadioShack and have them get you the correct battery. Use contact cement glue to put it back together.

If you are handy - open the phone and clean the flex pad connectors with a cotton swab and a little bit of isopropyl alcohol.
