For both the quite Sun and the Sun with radio bursts, when pointing directly to the Sun, the total power received by FAST would be out of the safe operational range of the signal chain, even resulting in the damage to the receiver. As a conclusion, the Sun should be kept at least $\\sim 2^{\\circ}$ away from the main beam during the observing at $\\sim 1.25 {\\ \\rm GHz}$. The separation for lower frequency should be larger.
