Cellular providers are updating their cellular networks and plan to shut down older 2G and 3G

networks. Some bedside transmitters rely on these networks to send implanted device data to clinics.

Only adapters that cannot connect to 4G networks are being replaced. Older, Sierra Wireless

885/888, Option Velocity GI0461, Sierra Wireless 313U, ZTE MF190, and Huawei MS2131 adapters will

be affected and need to be replaced. CELLUL AR COMPANY TRANSITION FROM 2G/3G TO 4G NETWORKS

No, the transmitter does not need to be replaced

Plug the bedside transmitter back into the electrical outlet. While your transmitter is powering up,

the LED lights on the front of the transmitter will scroll from left to right and the cellular adapter will

display a solid red light for a short time and then go off. Once the boot up cycle is complete, the only

light that will be illuminated will be the green power light on the front of your bedside transmitter.

There will be no light on the cellular adapter.

After connecting your new cellular adapter, the old adapter should not be plugged back into the

transmitter and does not need to be returned. You may dispose of the old adapter at your local

electronic waste recycling center.

Only the ZTE MF 833V adapters purchased on this site are configured to work with your bedside

transmitter and other adapters will not transmit the data to your clinic. It is important to use the

adapter that meets testing and qualification requirements to ensure the connectivity quality.

No, there is nothing wrong with your current adapter. Your current adapter may only be able to

connect with a 2G or 3G network. Because these are being shut down, you may need to use an updated

adapter to connect with a 4G network
