HF10 zoom goes without any explicit request

There may be moisture in the transmission fluid that is causing ice to block the valves. When the transmission is hot, change the fuid

this is some problem with the panel of buttons is your unit.

this will need some service from the company directly.

Camera has a poltergeist. Electronics are fubar. Time to replace since repair not cost effective.

You will have to take the camera apart and get to the back side of the connector. Most likely it is directly mounted to a circuit board. I am sure it is the board that is bad and not the connector itself. There should be a replacement number on the board itself.

it could be the free leaver is slipping on or dose the scooter look lopsided from the back if it is could be the axle i had that problem with mine stopped and started and was the axle an expensive repair but was worth it,or battries could be done,

This would be a fault in the zoom rocker switch and can usually be repaired fairly inexpensively. However, it’s not a user serviceable problem and will need to be diagnosed by a qualified service technician.
My name is Rick and I’m a professional repair technician with over 20 years in the business and have repaired many of these. I’m semi retired and work from home with little overhead so I can keep repair costs low. If you decide to have the camera repaired, please click HERE for a directory listing that suits your needs.

The calculator is not designed to quit on you without giving a fair warning: an error message. There are several Zoom functions, each with its specificities, so saying that the zoom function quit on you does not help a bit.
The safest Zoom you can use without any prior knowledge of the function is the ZoomStd (Zoom standard). It sets Xmin=-10, Xmax=10, Ymin=-10, Ymax=10. That is also what you get if you reset the memory.

You did not explicitly ask a question. Nonetheless I tried to answer with blinders on my eyes. If you still want to understand what you have been doig wrong with the Zoom, post a comment to this thread spelling out what you have been trying to do and the error message you got.

In computer networks, a proxy server is a server (a computer system or an application program) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.
A proxy server has many potential purposes, including:

• To keep machines behind it anonymous (mainly for security).[1]
• To speed up access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.[2]
• To apply access policy to network services or content, e.g. to block undesired sites.
• To log / audit usage, i.e. to provide company employee Internet usage reporting.
• To bypass security/ parental controls.
• To scan transmitted content before delivery for malware.
• To scan outbound content, e.g. for data leak protection.
• To circumvent regional restrictions.

A proxy server that passes requests and replies unmodified is usually called a gateway or sometimes tunneling proxy.
A proxy server can be placed in the user's local computer or at various points between the user and the destination servers on the Internet.
A reverse proxy is a (usually) Internet-facing proxy used as a front-end to control and protect access to a server on a private network, commonly also performing tasks such as load-balancing, authentication, decryption or caching

A firewall is a dedicated appliance, or software running on a computer, which inspects network traffic passing through it, and denies or permits passage based on a set of rules.
It is a software or hardware that is normally placed between a protected network and an unprotected network and acts like a gate to protect assets to ensure that nothing private goes out and nothing malicious comes in.
A firewall's basic task is to regulate some of the flow of traffic between computer networks of different trust levels. Typical examples are the Internet which is a zone with no trust and an internal network which is a zone of higher trust. A zone with an intermediate trust level, situated between the Internet and a trusted internal network, is often referred to as a "perimeter network" or Demilitarized zone (DMZ).
A firewall's function within a network is similar to physical firewalls with fire doors in building construction. In the former case, it is used to prevent network intrusion to the private network. In the latter case, it is intended to contain and delay structural fire from spreading to adjacent structures.
Without proper configuration, a firewall can often become worthless. Standard security practices dictate a "default-deny" firewall ruleset, in which the only network connections which are allowed are the ones that have been explicitly allowed. Unfortunately, such a configuration requires detailed understanding of the network applications and endpoints required for the organization's day-to-day operation. Many businesses lack such understanding, and therefore implement a "default-allow" ruleset, in which all traffic is allowed unless it has been specifically blocked. This configuration makes inadvertent network connections and system compromise much more likely.

Are you using Ni-MH batteries? Most other batteries including Ni-Cad just dont have the punch that the Ni-MH has amperage wise. You could try Lithium batteries, but many devices are explicit on the battery type.

Try take battery off camera while operating recording mode, amd put it back without turning off camera. I really do not know why this happend, but this solved my Canon mvx330i "by it self zooming" problem. try turn on digital zoom in meny and take of battery...
