1.產(chǎn) 品 詳 情 資 料：
每當(dāng)：?PM8xx B（電池）LED閃爍或熄滅時(shí)，必須更換電池。?多次或長(zhǎng)時(shí)間停電。?由于維護(hù)或故障，系統(tǒng)停機(jī)時(shí)間延長(zhǎng)。為安全起見，僅在AC 800M通電時(shí)更換電池。更換內(nèi)部電池：1。使用刀片螺絲刀，從PM8xx上松開固定螺釘，然后拆下右側(cè)蓋。2.識(shí)別并拆下內(nèi)部電池。3.重新建立電源時(shí)，確保B（電池）LED點(diǎn)亮4。更換PM8xx右側(cè)蓋并擰緊螺釘。5.以經(jīng)批準(zhǔn)的方式處理耗盡的鋰電池。根據(jù)外殼上的標(biāo)記，插入可維修的電池并檢查電池極性和方向是否正確。SB821外部電池單元外部電池安裝在SB821內(nèi)部電池單元內(nèi)。由于電池不可再充電，因此定期更換電池非常重要（有關(guān)更多詳細(xì)信息，請(qǐng)參閱維護(hù)頻率表）。為了接近電池和外殼，取下蓋子（參見第196頁圖65）。更換電池時(shí)，務(wù)必檢查極性和方向是否正確。
The battery must be exchanged whenever: ? The PM8xx B(attery) LED flashes or is extinguished. ? Multiple or extended power cuts have occurred. ? Extended periods of system downtime have occurred for maintenance or malfunctions. For reasons of safety, exchange the battery only when the AC 800M is powered up.To exchange the internal battery: 1. Using a blade screwdriver, release the captive screw from the PM8xx and remove the right-hand cover. 2. Identify and remove the internal battery. 3. When power is re-established, ensure that the B(attery) LED is illuminated 4. Replace the PM8xx right-hand cover and tighten the screw. 5. Dispose of the run-down Lithium battery in an approved manner.Insert a serviceable battery and check that battery polarity and orientation are correct, according to the marking on the housing.SB821 External Battery Unit The external battery is mounted inside the SB821 External Battery unit. Since the battery is not rechargeable, it is important to exchange it on a regular basis (refer to the Maintenance Frequency Schedule for further details). For access to the battery and housing, remove the cover (see Figure 65 on page 196). When replacing the battery, be sure to check that polarity and orientation are correct.
