Expert Pro - Remote control battery issue - daniel.avasilichioaei - 27-Dec-2018

Did you ever check the evolution in time of remote control batteries voltage level? Or did you ever check batteries voltage when remote stops working normally?

I found the same issues on two different Expert Pro remote controller:
1. I tested the remote control without one of the batteries, by rotation. I was surprised to find that the remote is working normally without the bottom battery! But it does not work without the top or mid battery.
2. Power/voltage consumption of top and mid batteries is ~20 times bigger than consumption of bottom battery. When remote stops working normally, the top and mid batteries are empty, and the bottom battery is full (apparently not used).

Practically, both of the remotes that I have seems to use only 2 of the 3 batteries. Of course, the remote has a very short battery life (~1.5 months).


Did anyone encountered this issue?...

Hello, I can not confirm! I change the batteries once a year (Expert is in daily use). But I use high quality batteries (Duracell / Ultra Power Alkaline).

Did you measure the battery voltage after a few weeks/months of usage?

The batteries have been in operation for 10 months! Will the batteries measure. Result I post then!!

Hello, the batteries just measured:
Batt-1 = 1,04 volts
Batt-2 = 1,03 volts
Batt-3 = 1.04 volts
I think that their remote controls are broken!

You may have a fault I had with my 220 controller. I found it discharged the batteries within a few weeks regardless of use. Devialet told me they had not come across this fault before but they requested a return of the remote and sent me a posting label. They returned it to me within a week and all worked fine thereafter. Your remote battery life should last a very long time. If it doesn’t, get your remote attended to. Talk to Devialet about it. Measuring voltage of AA battery cells is totally unreliable and inconsistent.

Simply, if your remote does not work as expected, contact them and get it repaired.

My remote works at ~8m. I cannot check a longer distance.

I had a similar issue when i had my D120 upgraded to a 220 Pro. The range of the remote was very poor compared to the original - even with brand new batteries and had a few other funnies with the volume going up and down on its own. After the whole lot went back to France for the CI board, the remote was as good as the when i first had it. Might be worth contacting Devialet to get it checked out.

The Remote of my 440-Pro is consuming excessive battery power with a fresh set of AAA x 3 Duracells lasting barely 6 weeks (1-2 months). I opened a ticket with Customer Service which I believe is now located in Australia and also spoke to the Devialet USA guys at their Greene Street, Manhattan, New York Store but they said they can't replace the Remote with another one as all Expert / Expert accessories are handled only in Paris so Devialet might send me a shipping label for me to ship out the Remote to Paris.

1. Any inputs as to how long does this turnaround process take ?

2. How does one use the 440-Pro without the Remote (whilst it is away) if at all it's possible ?

If you're just wanting to control power-on, source, and volume, it can be done via the remote app (at least on my iphone/ipad).

I have a D200 that I purchased as a D170 when they first came out.
I think that was around 6 years ago maybe a little longer.
I use it a minimum of 5 days a week.
My family use it as well.
Remote recently started being slow to respond to changes in volume.
The batteries in the remote were the original ones - never replaced.
I have been expecting that replacement will be immanent for several years and now that day has finally come. 
Those original batteries were Duracell Plus Power batteries - made in Belgium - with an expiry date of March 2019.

Some new batteries restored responsiveness.
