Page 3 Chapter 2: Getting Started Charging the Scanner’s Battery In order to operate the Scan ner and th e 2-Way Injector f rom battery power, the battery must f i rst be charged . You can run th e units f rom the A C adapter u n til the charg i n g cycle is complete.
To remove th e Ni-Cd battery pack, p lace the Scann er o r Injector face d own and slide the arro w- shaped tab downward . Then lif t the battery pack up towards you . To in stall the battery pack, in sert the two tabs o n the to p o f the battery in the Scanner an d press do wn on th e battery pack until it clicks into plac e.
Page 5 To put your 2-Way Injector or 2-Way Injector+ into Refresh Mode, f i rst attach the Injector to your Scann er with a RJ-45 o r 36-p in cable, which ever is approp riate f o r your eq u ipment (you may need to us e an a dapte r if your unit s hav e differe nt conne ctor type s).
High Voltage Protection The PentaScanner +/ PentaScanner / PentaScanner Cable Admin, 2- Way I nj ect or+/ 2- Way Injector and Super Injector+/Super I njector are designed to withstand in put hazard vo ltage conditions that arise from norm al te lephony a pplications such a s 48 VD C at less t han 80 ma or 24 VAC used to power man y keysets.
