Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.
Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.
some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks
Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
I will definitely be back for more information when I need it.
NUDOS NiMH shavers
HQ4850 The green LED â+â goes on. If the cells are almost empty the red LED â-â will go on as well. When the red LED goes out, there is enough capacity for one cordless shave of approx. 3 minutes. After 60 minutes the green LED starts to blink, to indicate that the cells are full. The signals during shaving are described under âALLâ. HQ3870 + HQ4870 One of the LEDs of the capacity indicator will start to blink. If the cells are almost empty, the block â20â will be red. When it turns green, there is enough capacity for one cordless shave. Each time when another 20 % of the full charge has been reached, the next block of the indicator will start to blink. After 60 minutes, the â100â block starts to blink. This LED stops to blink as soon as shaver is fully charged. If charging is continued (in the 25 mA mode now), the IC will force the PM to supply 1000 mA for half a sec. every 10 secs to compensate for the continuous burning of the LEDs. When switching on and off, the actual capacity is shown for approx. 8 seconds. After shaving cordless with a fully charged shaver for some time, the â100â LED will be no longer visible. Then, the other blocks will gradually disappear one by one. The next signal is described under âALLâ. HQ4890 The green LED goes on and one segment of the LCD will start to blink. If the cells are empty, this will be the â20â segment. The red LED will remain on until there is enough capacity in the cells for one cordless shave of approx. 3 minutes. Each time when another 20 % of the full charge has been reached the next segment will start to blink. After 60 minutes the word âFULLâ and the green LED start to blink. When shaving cordless with a fully charged shaver, first âFULLâ will disappear. After some time the â100â segment will disappear, etc. Finally, a blinking â20â segment will show together with the red LED, as described below. ALL During discharging the capacity counter counts down proportional to the motor current. When the counter reaches the âzeroâ state, a Nearly Empty Indication (NEI) is given by the red LED. After the shaver has been switched off the red LED will blink for 4 seconds. If the shaver is not in use, the counter will count down at a slow rate during approx. 100 or 200 days, to compensate for the self-discharge of the cells and the power consumption of the ICs (100 days at Tamb>35ËC, 200 days at Tamb<35ËC).
