What is the Specific Absorption Rate (SAR)?

What is the SAR?

The SAR (specific absorption rate) is an indicator of the amount of energy transported by radiofrequency waves absorbed by the mobile phone user.

The value SAR indicates the maximum exposure that the device may produce. The unit of SAR is watts per kilogram (W/kg). Within the European Union, the limit for a GSM is 2 W/kg.

SAR values are classified by category. These are indicated next to each of our devices offered for sale:

CATEGORY A: SAR values lower than 0.4 W / kg

CATEGORY B: SAR values equal to or higher than 0,4 W/kg but lower than 0,8 W/kg

CATEGORY C: SAR values equal to or higher than 0,8 W/kg but lower than 1,2 W/kg

CATEGORY D: regarding SAR values equal to or higher than 1,2 W/kg but lower than 1,6 W/kg

CATEGORY E: regarding SAR values equal to or higher than 1,6 W/kg but lower than or equal to 2 W/kg

Take care of your health - use your cell phone in moderation, prefer the use of a headset and choose a device with a weak SAR value.

What are the advantages of fibre optics?

The bandwidth potential of fibre optics is vastly superior to copper pairs. In contrast to ADSL, fibre optic signals do not deteriorate over distance (from the ADSL connection to the telephone exchange). Therefore, you can benefit from a very high bandwidth transmission, for outgoing and incoming data. Furthermore, fibre optics are not effected by electromagnetic interference. If you decide for a small bandwidth based on fibre optics today, you can easily upgrade your product to highest speed at any time.

What do I get with my current CakeMail plan included in Join MS webdesktop?

With your current CakeMail plan you can have up to 1000 contacts and send up to 10000 emails per month. This means that if you have 1000 contacts and send email to all of them at one time, you are using 1000 emails of the total of 10000.

"Access Denied" error received during some of the backups. What can be done?

This is a known issue when the encrypted files/folders are skipped with “Access Denied” error in the product. Our software does not support backup of encrypted files as it needs to read these files on a binary level and this is not possible when files are encrypted.

As workaround you can disable the encryption for the folders/files.

What do the Sender/Recipient Whitelist/Blacklist terms mean?
  • Sender Whitelist/Blacklist - This refers to lists of email addresses/domains of people sending mail to the user. Sender Whitelist (normally available at domain level)

 All filtering checks are disabled for whitelisted senders. You can whitelist a specific sending email address, or a full sending domain. We recommend only using the sender whitelist if the system would otherwise wrongly block email from a certain sender. Spammers often use fake senders matching the recipient domain, or domains the recipient may have received emails from before, to try and bypass the filtering in that way. In addition, if the system is generally wrongly blocking a sender, you can always contact our customer support so we can research what problem is causing the rejection and resolve that issue.

  •  Sender Blacklist (normally available at domain level)

 Emails from senders listed on the blacklist will be automatically rejected. The messages are NOT quarantined. The messages are rejected with a 5xx SMTP error code, so legitimate sending SMTP servers will generate a bounce message to the sender.

  •  Recipient Whitelist/Blacklist - This refers to lists of email addresses / domains of people to whom mail is sent. Recipient Whitelist (normally available at domain level and email level)

 Filter checks are disabled for listed addresses; Email directed to whitelisted recipients will bypass all filters. Recommendation is to use only for exceptional cases such as abuse@ or postmaster@.

  •  Recipient Blacklist (normally available at domain level)

 Emails to recipients listed on the recipient blacklist will be automatically rejected. The messages are NOT quarantined. The messages are rejected with a 5xx SMTP error code, so legitimate sending SMTP servers will generate a bounce message to the sender.
