II. Operation (CONT)
7. IN CASE Of EMERGENCY
Dial 911 on the phone pad and wait until the operator answers. All 911 centers
are answered by a staff person who determines if the call is a voice or TTY
call. Move the unit down to the mouthpiece and press voice button. Wait until
you see the message indicating it is finished, then move it back to the earpiece.
Now you can talk to the Emergency operator and you can read the message
from 911 on the display.
Note: Krown Manufacturing makes no representations that the 911 service will
properly respond to a TDD/TTY call.
8. USING THE PVCO WITHOUT RELAY ASSISTANCE
If you know the hearing person has a TTY acoustic coupling with a telephone
you can dial them direct without calling Relay service. Explain to the hearing
person how PVCO works. The hearing person will listen to your voice and type
back the answer by using their TTY/TDD. The PVCO user should wait
approximately 3 seconds after seeing “GA” to speak. This time allows the
person using the TTY the opportunity to pick up from and connect to the TTY
without missing any of the conversation. It also ensures the conversation
between you and the caller is strictly private.
9. USING THE PVCO WITH A CELL PHONE
The PVCO-C is modified to work with select digital cellular phones or cordless
phones with a headset output. Consult your cellular phone manual for how to
set up TTY/TDD mode. Set your cell phone to work with TTY compatible
mode. Plug the communication cable to the cellphone and the PVCO-C.
First turn on the power for the PVCO-C and the mobile phone. Second, dial
a TTY number or your State Relay Service on the mobile phone keypad.
Watch the LED on the PVCO-C for calling progress. If you did not see any
action for 15 seconds, hang up and redial that number. Third, waiting for the
other party to answer your and end by a “GA”. It’s your turn to speak. Hold the
PVCO-C close to you and speak clearly. Always end by saying GA or go
ahead. Continue the conversation until both parties are ready to hang up. Hang
up the mobile phone and turn off the PVCO-C.
