Basic Operations
The following topics outline basic features and operations of your device.
Basics
The following topics offer an overview of your device’s basic operations.
Device Installation
The Phone Connect 4 works with your wireless service provider’s cellular network instead of your phone
jacks.
Put the Phone Connect 4 in a place where there is a strong signal from a signal tower, typically near a
window or outside wall.
Connect the Device to a Phone
This topic outlines how to connect a phone to your Phone Connect 4.
1. Unplug your phone from the phone wall jack.
2. Plug your phone into the ‘PHONE 1’ port on the device using the phone cable.
Basic Operations 9
Note: The “Phone 2” port can be used to connect an additional phone, or cordless base station. All
telephones connected to the Phone Connect 4 will use the same telephone number.
Make a Test Call
Once you have connected a phone to the Phone Connect 4, make a call to confirm your service.
1. Use the connected phone to dial a phone number.
2. Wait a few seconds for the call to be connected.
Note: You will need to dial 10 digits (area code plus 7-digit phone number) even for local numbers.
Voicemail
Your Phone Connect 4 supports wireless voicemail. Follow the steps below to set up and use your
voicemail.
Voicemail Setup
1. Dial *86 on any home phone connected to your device to be connected to your wireless
voicemail.
Your phone dials the voicemail access number.
2. Follow the system prompts to:
Create your passcode.
Record your name announcement.
Record your greeting.
Important: Voicemail Passcode – It is strongly recommended that you create a passcode when setting
up your voicemail to protect against unauthorized access. Without a passcode, anyone who has access
to your phone is able to access your voicemail messages.
Message Waiting
There are two indicators for a new message waiting: 1) the voicemail indicator ; and 2) an
intermittent dial tone.
■ The voicemail indicator on your device flashes when a voicemail message is waiting. You will
also hear an intermittent dial tone on any connected phone handset before placing a call.
Retrieving Messages
1. To retrieve voice messages, dial *86 on any home phone connected to your device and wait
about few seconds to connect to your wireless voicemail box.
2. Simply follow the voice prompts to listen to and manage your messages. (Alternately, you may
dial your 10-digit home phone number to access your voicemail box.)
Basic Operations 10
Calling
The following topics explain how to make phone calls and use other calling options with the Phone
Connect 4.
Making a Call
Using a phone connected to your device allows you to place and receive calls as you normally would.
The device supports both cordless and corded phone dialing methods.
Note: Make sure to dial the 10-digit phone number, including area code.
Adjusting Volume
You can adjust call volume using the volume controls of any connected phone. You can also adjust call
volume using the Phone Connect 4 menus.
1. When you are on a call, press ** or ## to enter Volume Setting Mode.
2. Press * or # to turn volume down or up.
3. Press any other key or wait 5 seconds to exit Volume Setting Mode.
Note: Four volume levels are available (level 1 to level 4). When you're at the highest level 4 or lowest
level 1, you can't adjust the volume anymore and will hear the indicating voice.
Your home phone(s) may have a separate volume level setting function that is independent of the Phone
Connect 4.
Three-Way Calling
With 3-way calling, also known as conference calling, you can talk to two people at the same time. When
using this feature, the normal airtime rates will be charged for each of the two calls.
1. While on an existing call, press the Flash (or Talk) key on your phone to put the first party on
hold. When you hear a dial tone, dial the second party’s number.
2. When the second party answers, press the Flash (or Talk) key again to complete the three-way
connection. If the second party does not answer, press the Flash (or Talk) key to end the
connection and return to the first party.
Notes: If your phone does not have a Flash (or Talk) key, use the off-hook mechanism supported by
your phone instead.
If one of the people you called hangs up during your call, you and the remaining caller stay connected. If
you initiated the call and are the first to hang up, all callers are disconnected.
Call Waiting
When you’re on a call, Call Waiting alerts you to incoming calls by sounding two beeps.
■ To hold the current call and accept the waiting call, press the Flash (or Talk) key. You can press
the Flash (or Talk) key anytime to switch back and forth between calls.
Basic Operations 11
For those calls where you don’t want to be interrupted, you can temporarily disable Call Waiting by
pressing *70 before placing your call. Call Waiting is automatically reactivated once you end the call.
Notes: Your device comes with standard three-way calling and call waiting. Operation of these features
will vary depending on your home phone equipment.
If your phone does not have a Flash (or Talk) key, then use the off-hook mechanism supported by your
phone.
Call Forwarding
Call Forwarding lets you forward all your incoming calls to another phone number – even when your
phone is turned off. You can continue to make calls from your phone when you have activated Call
Forwarding.
Note: You are charged a higher rate for calls you have forwarded.
Always forward

2. Dial the 10-digit number to which you wish to forward your calls.
3. Press the “#” key.
Example: *721234567890# forwards your calls to the phone number 123-456-7890.
4. Wait for about 3 seconds until you hear a confirmation tone for the forwarding process to
complete before hanging up.

answer the calls for 10 seconds.
4. Wait for 3 seconds until you hear a confirmation tone for the forwarding process to complete
before hanging up.
Note: Press *730 to un-forward calls.
TTY Mode
A TTY (teletypewriter, also known as a TDD or Text Telephone) is a telecommunications device that
allows people who are deaf, hard of hearing, or who have speech or language disabilities, to
communicate by telephone.
Your Phone Connect 4 is compatible with select TTY devices. Please check with the manufacturer of your
TTY device to ensure that it supports digital wireless transmission.
Your device’s TTY mode is set to TTY Off.
● TTY Off: Users who can hear and talk can disable TTY support.
● TTY Full: Users who cannot talk or hear may use this mode to send and receive text messages
through TTY device.
● TTY HCO: Users who can hear, but cannot talk, may use this mode to listen to conversation of
the other party, and respond via text messages.
● TTY VCO: Users who can talk, but cannot hear, may use this mode to talk through the phone and
receive responses via text messages.
Warning: 9-1-1 Emergency Calling
It is recommended that TTY users make emergency calls by other means, including Telecommunications
Relay Services (TRS), analog cellular, and landline communications. Wireless TTY calls to 9-1-1 may be
corrupted when received by public safety answering points (PSAPs), rendering some communications
unintelligible. The problem encountered appears related to TTY equipment or software used by PSAPs.
This matter has been brought to the attention of the FCC, and the wireless industry and the PSAP
community are currently working to resolve this.
