The V810 provides 2 telephone ports (RJ11). Plug the telephone cord into one of the telephone ports on the back of your device. The other end of the cord must remain plugged into the back of your telephone unit. Telephones sold separately.

Remove the battery cover from the back of your V810. Lift the battery holder. Install the SIM card into the spring-loaded SIM slot. To remove a SIM, press the edge of the SIM inward and the SIM will pop outward from the SIM slot. Refer to the Quick Start Guide or User Guide for more details.

Your V810 can be in 3 different power modes, battery-only, AC power only, or AC power with batteries installed. Your V810 comes with 3 AA batteries. Optional Ni-MH rechargeable battery pack can be purchased through ATEL USA.

To Perform a Power Reset:

a) Using the Power button: Press and hold the power button for 10 seconds until the V810 restarts.

b) If your V810 is in Battery-only mode, remove the batteries for 10 seconds and then re-install the batteries.

c) If your V810 is in AC power only mode (only plugged into the wall charger), unplug the wall charger for 10 seconds and then plug the wall charger back. If your V810 is plugged to the wall charger AND installed with batteries, unplug the wall charger AND remove the batteries for 10 seconds. Then, plug the charger back and re-install the batteries.

Using the RESET pin hole: Remove the back cover. Make sure your V810 is powered on. Use a unfolded paper clip, insert it into the RESET pin hole and push down for 3 seconds, then release. Your V810 will perform the reset and restart automatically.

Make sure the AC power adapter is properly connected to both the unit and the wall socket. Check to make sure the telephone cable is securely plugged into both the phone and the V810 unit. Check the screen to make sure at least one of the signal strengths is lit up. Check with your SIM provider to make sure that service is activated and provisioned for this type of voice device. Note that a dial tone will only be available and heard when the device is connected to a network.

If the telephone connected to your V810 has an answering device, you can set it to pick up after fewer rings before the call goes to the voice mail. Turn off your answering device if you would like to use the voice mail service. Please refer to the user manual and setup material provided by the answering machine manufacturer for instructions.

You can use the telephone connected to your V810 to make 911 calls. For better GPS location accuracy, place your V810 near a window.

Note: ATEL cannot guarantee the voice or E911 calls availability. Making a successful call depends on your hardware (telephone) availability, physical location, wireless signal strength, and/or network services. You should never rely solely on any wireless mobile device for essential communications (medical emergencies, for example). When making
an emergency call, remember to give all the necessary information as accurately as possible.

While the V810 has backup batteries, if the phone connected to it requires external power to operate, service (including the ability to make and receive 911 calls) will not be available during a power outage. Service will only be available during a power outage if the phone connected to the device does not rely on external power to operate (as is
the case with many corded phones).

Talk usage time on the AA backup batteries is approximately 3 hours and standby time is approximately 30 hours. Actual values can vary with environmental conditions, connectivity and other usage-related circumstances.

Note that the batteries can be replaced with new AA batteries for continued use.

Your V810 displays the phone number for incoming and outgoing calls. If the telephone connected to your V810 supports the Caller ID function, the telephone displays the caller’s phone number and/or name before you take the call. Contact names stored on your telephone may be displayed for incoming calls. Please consult with your service provider for more info on the Caller ID feature (additional charges may apply).

Call forwarding allows you to forward incoming calls to another phone number and this feature may be supported by your carrier/service provider. Please contact your service provider for more details.

You can adjust the volume using the telephone connected to the V810. Refer to your telephone user manual for more details.

Check the number to ensure you’re dialing correctly, without pauses longer than four seconds between dialed digits.
