Details of complaint: the biomedical engineer (bme) reported that the gz transmitter in hi-q view disconnected from the g9 monitoring unit without warning on 08/03/2023.There were no reports of patient harm.Nkc reviewed the logs and confirmed that the central nurse's station (cns) displayed an error message stating "telemetry not connected" due to the battery being discharged, leaving no power to the gz transmitter or moving it out of the wireless lan range.Investigation summary: investigation of the device logs for the cns sn:(b)(6).Was able to confirm that the cns received a "telemetry not connected" error which would indicate that the connection between the gz and the g9 was lost.This error was a result of the gz losing power.It was concluded that the two probable causes for no alarm for low battery and/or "telemetry not connected" error message are related to the use of unspecified batteries.The batteries recommended in the operator's manual of the gz-130p are the only batteries that were verified to operate well with the device.The internal resistance of the battery will determine how well it operates with the gz-130p, and it cannot be determined with battery specifications alone.The root cause has been identified as the use of non-specified batteries.There is no evidence of an nk device malfunction that may have contributed to the reported issue.The customer had changed the type of batteries used to resolve the issue.The following fields contain no information (ni), as attempts to obtain information were made, but not provided: a2 - a6 b6 b7 attempt # 1: 08/16/2023 emailed the bme for the patient information: no reply was received.Attempt # 2: 08/22/2023 emailed the bme for the patient information: no reply was received.Attempt # 3: 08/24/2023 emailed the bme for the patient information: no reply was received.Additional device information: d10 concomitant medical device: the following devices were used in conjunction with the gz transmitter: cns: model #: pu-681ra.Serial #: (b)(6).Device manufacturer data: 27/08/2020.Unique identifier (udi) #: (b)(4).Returned to nihon kohden: na.G9 monitoring unit model #: cu-192r.Serial #: (b)(6).Device manufacturer data: 03/09/2020.Unique identifier (udi) #: (b)(4).Returned to nihon kohden: na.
