For RESU 7H and RESU10H (Type C and Type R). There are two methods to check the serial number, which appears in two places. 1. Underneath the battery, adjacent to the cable entry. By using a smartphone, you can photograph this label. You could try selfie mode. Please note that with this method, it may not be possible to capture the QR code, meaning you need to transcribe the serial number manually. 2. Behind the access cover at the right bottom side of the battery. To access: (i) Open the two latches by pressing the child-proof tab with your thumb before unlatching. (ii) Remove the access cover by opening slightly (2-10 degrees) and lifting off. Be sure to lift the door off - it is not hinged. (iii) You can then see the serial number label on a clear plastic cover. You can either photograph and transcribe it manually or, if your smart-phone has QR capture, direct it at the QR code to capture as text. (iv) Reattach the cover by holding in place and re-latching. For RESU3.3, RESU6.5, RESU13 and RESU10 It is not always possible for customers to directly determine the serial number, due to its location underneath battery cables, but you may attempt before turning to the alternative options outlined below. To determine the serial number directly: i. Look to the right side of the battery. ii. You may see the serial number label partially obscured by battery cables and/or conduit. You can either photograph and transcribe it manually or, if your smart-phone has QR capture, direct it at the QR code to capture as text.
