74. Headset Operating-Mode Settings Most stores have installed systems with Hands-Free capability, but some have not. If you are uncertain whether or not your System 500 has Hands-Free capability, do the following test. a. Auto-Hands-Free Setting The auto-hands-free (AHF) feature allows one operator to communicate with a customer in one drive-thru lane without pressing any buttons. Other operators can listen. If the first operator turns the AHF feature off, another operator can turn it on. CAUTION: Only one HS500 per lane can be set in the auto-hands-free mode, or interference will occur when a customer enters the drive-thru lane. • With the power already on, press and hold the Power button and touch the Volume-down button — You will hear “Auto-hands-free on” or “Auto-hands-free off” NOTE: You must touch the Volume-down button within 2 seconds after pressing the Power button, or you will turn the power off and have to begin again. If the auto-hands-free feature does not come on, you may need to reconfigure the S1 switch in the base station. Call HME Customer Support at 1-800-848-4468 for assistance. • The last auto-hands-free on/off message you hear will remain in effect until you change it again or turn the headset power off. b. Configuration Settings • With the power already on, press and hold the Power button and press the B button. NOTE: You must press the B button within 2 seconds after pressing the power button, or you will turn the power off and have to begin again. • You will hear “Configuration” in the headset. • Select the desired configuration setting described below. • When finished, press and release the B button to exit the configuration-settings mode. You will hear “Power on, lane (one or two)” in the headset. • Configuration settings will remain in effect until you change them again. Hands-free On/Off Configuration • Touch and release the Volume-down button — you will hear “Hands-free on.” • Touch and release the Volume-down button again — you will hear “Hands-free off.” • You will continue to hear “Hands-free on” or “Hands-free off ” messages alternating each time you touch and release the Volume-down button. When a car is at the speaker post (or menu board), touch and hold the appropriate “A” button. If you can hear the sound of the car or the customer with the “A” button held, you have Hands-Free capability.
