CHAPTER 6 (CONTINUED)

H. Lock

The Q90 has a LOCK switch on the right side. Turn the LOCK ON to prevent the Q90 from accidentally turning on and draining the battery. We

strongly advise you turn the LOCK ON any time

you move the Q90 from one place to another or

carry it in your luggage

or briefcase. Remember to turn the LOCK OFF before using your Q90.

I.Useful Tips

1.Background sounds will interfere with a VCO or HCO call, so it is very important to make these calls in a quiet area. During an HCO call, your caller should also be in a quiet room.

2.You can make VCO and HCO calls using a cordless or cellular phone.

3.When using a cellular phone for VCO calls, turn the Hi-Speed mode OFF.

4.During a VCO or HCO call, if you suspect there is static or other noise on the phone line, turn the Hi-Speed mode OFF.

5.For VCO calls, make sure the green color microphone indicator is ON before you speak.
