Overview of Checking the Mnemonic Backup on the Trezor Hardware Device

Why Is It Always A Good Idea To Check the Mnemonic Backup Phrase Before Depositing Coins To the Wallet?
Consider the following:
Is is better to KNOW that your mnemonic backup phrase will work, to recover your wallet, or is it better to HOPE that your backup phrase will work, when you NEED to recover your lost or damaged wallet?
The Steps to Checking the Recovery Phrase
1) We select the number of words that make up our mnemonic backup phrase. This can be 12, 15 or 24 for the Trezor One, or as many as 33 words for the Trezor Model T.
Typically, we will have a 12 or 24 word mnemonic backup phrase.
2) Next, we will select either a Standard or Advanced recovery check.
The Standard Recovery Check consists of the Trezor device requesting a word from a random position in the list.
In Trezor Suite you enter the word that you have in the corresponding number position from your Recovery Sheet and select it.
This process continues until you have entered all of the words from the Recovery Sheet.
The Advanced Recovery Check consists of you entering each word from your Recovery Sheet in order, by spelling the word one letter at a time.
This is done by selecting each letter from a selection displayed on the device, on a grid. You select the correct letter or range of letters that your current letter falls in, until you are presented with a short list of potential valid words, of which you select the valid word.
3) Once all of the words have been entered, the Trezor Suite application will compare the generated Primary Key to the Primary Key currently on the Trezor device.
If they match you will see a success message and can rest assured that you will be able to recover your wallets on the Trezor device in the future.
If an error occurs, you may have selected an incorrect word or entered a word in the incorrect order and you should test the recovery words again.
If you still get an error then you may have the incorrect Recovery Sheet words for the device you are testing.
In any case the Check Backup process has NO impact on the Primary Key that is currently held on the device.
