Basic Troubleshooting for the US Cat S48c

Please note this device has an embedded battery that must only be accessed by authorized personnel.

Device will not charge.

1. Verify the charger and charger cable used is a Cat charger (the one that came with the phone).
2. If the battery is completely depleted, it may take 30 minutes for the phone to indicate charging on the display.
3. Attempting to force a USB Micro connector into the USB Type C socket into the phone will likely damage the charging port and prevent the phone from charging – see figure 1. If there are broken, bent, or missing pins inside the USB port, the phone will need to be evaluated by our repair center.

Device will not turn on, screen is blank, or is unresponsive. 

1. Ensure the phone is fully charged using the original Cat wall charger and USB cable. If the issue continues after confirming the phone is charged, move to step 2 to reset the phone.
2. To reset the device, open the SIM and SD card door, behind the door to the right is an “OFF” button (in a small hole).
3. Gently depress this button (with the end of a paper clip) for 20 seconds and the device will power down, and restart. Device should now power on and perform as expected.
4. If you continue to have trouble, see page 2 of this insert for additional assistance.

Device displays “No service” or will not connect to the internet.

1. This may be displayed if you are in an area that is not covered by your network provider, or if you are in an area of poor reception. For example, an enclosed area, basement, or around tall buildings.
2. No service will be displayed on your screen until the situation is resolved by relocating to an area of service.
3. If this problem persists when in a known good service location, contact your network provider to ensure there are no restrictions on service or your SIM services.
4. If you experience signal issues at all locations, see below for additional assistance.

If you continue to have trouble with your Cat S48c
Contact our US support office by calling 1 646 568 9682.  Our support team may be able to provide additional assistance and if necessary, confirm warranty status, and setup a repair for your device.  If after any additional troubleshooting the issue remains, you will be instructed to send the device to our repair center.  Our contact center will request either the 14 or 15-digit IMEI number from your device.  The IMEI can be obtained via these methods: 

• Type *#06# into the phone’s dial pad. The 15-digit IMEI will appear on the screen of the phone.
• The IMEI is also beneath the SIM/SD Card door on a black plastic label that slides out from the phone. With the SIM door open and facing down, gently shake the device and the label should slide out. Do not pull on the label as it may break away from the phone.

Our support team will then direct the creation of a return merchandise authorization number (RMA number) which you will receive via email along with shipping instruction. Prior to sending the device to our repair center, ensure the following have been completed:

1. All user data has been backed up.
2. Both the SIM and SD cards have been removed from the phone. Do not send these with the device.
3. The device is securely packed in a padded envelope or box to ensure it is not damaged in transit.
4. A copy of the proof-of-purchase receipt is included with a brief description of the issue.
5. IMPORTANT: Please ensure you copy the RMA number on the front/sides/back of the shipping package.

If the device is under warranty, the repaired device should be returned approximately 5 business days after receipt by our repair center.
